  • How to run a jar file in hadoop

    - by Arihant
    I have created a jar file using the java file from this blog using following statements javac -classpath /usr/local/hadoop/hadoop-core-1.0.3.jar -d /home/hduser/dir Dictionary.java /usr/lib/jvm/jdk1.7.0_07/bin/jar cf Dictionary.jar /home/hduser/dir Now i have tried running this jar in hadoop by hit and trial of various commands 1hduser@ubuntu:~$ /usr/local/hadoop/bin/hadoop jar Dictionary.jar Output: Warning: $HADOOP_HOME is deprecated.

  • Looking for an algorithm to connect dots - shortest route

    - by e4ch
    I have written a program to solve a special puzzle, but now I'm kind of stuck at the following problem: I have about 3200 points/nodes/dots. Each of these points is connected to a few other points (usually 2-5, theoretical limit is 1-26). I have exactly one starting point and about 30 exit points (probably all of the exit points are connected to each other). Many of these 3200 points are probably not connected to neither start nor end point in any way, like a separate net, but all points are connected to at least one other point. I need to find the shortest number of hops to go from entry to exit. There is no distance between the points (unlike the road or train routing problem), just the number of hops counts. I need to find all solutions with the shortest number of hops, and not just one solution, but all. And potentially also solutions with one more hop etc. I expect to have a solution with about 30-50 hops to go from start to exit. I already tried: 1) randomly trying possibilities and just starting over when the count was bigger than a previous solution. I got first solution with 3500 hops, then it got down to about 97 after some minutes, but looking at the solutions I saw problems like unnecessary loops and stuff, so I tried to optimize a bit (like not going back where it came from etc.). More optimizations are possible, but this random thing doesn't find all best solutions or takes too long. 2) Recursively run through all ways from start (chess-problem-like) and breaking the try when it reached a previous point. This was looping at about a length of 120 nodes, so it tries chains that are (probably) by far too long. If we calculate 4 possibilities and 120 nodes, we're reaching 1.7E72 possibilities, which is not possible to calculate through. This is called Depth-first search (DFS) as I found out in the meantime. Maybe I should try Breadth-first search by adding some queue? The connections between the points are actually moves you can make in the game and the points are how the game looks like after you made the move. What would be the algorithm to use for this problem? I'm using C#.NET, but the language shouldn't matter.

  • Cisco 891w multiple VLAN configuration

    - by Jessica
    I'm having trouble getting my guest network up. I have VLAN 1 that contains all our network resources (servers, desktops, printers, etc). I have the wireless configured to use VLAN1 but authenticate with wpa2 enterprise. The guest network I just wanted to be open or configured with a simple WPA2 personal password on it's own VLAN2. I've looked at tons of documentation and it should be working but I can't even authenticate on the guest network! I've posted this on cisco's support forum a week ago but no one has really responded. I could really use some help. So if anyone could take a look at the configurations I posted and steer me in the right direction I would be extremely grateful.

  • Why do clients on Branch Sites insist on accessing SYSVOL on the HQ DC instead of the branches' RODC?

    - by pepoluan
    I'm still scratching my head over this situation... You see, we have 3 RW DCs in the HQ, and 1 RODC on every branch sites (50+ locations). During startup, a script will pull in some files from \\example.com\SYSVOL\example.com\Common\Data But we have been experiencing bandwidth overload. A traffic analysis indicated that lots of clients in the Branch Sites were trying to access the SYSVOL located in the RW DCs. E.g.: If the RW DCs are 10.1.0.15, 10.2.0.15, and 10.3.0.15, and site 'X' has a subnet of 10.27.0.0/16 (with its RODC at 10.27.0.15), clients at site 'X' seem to insist on accessing \\10.1.0.15\SYSVOL or \\10.2.0.15\SYSVOL or \\10.3.0.15\SYSVOL; they seem to be ignoring the RODC completely. What is going on here? Where should I start investigating what went wrong? BTW, I'm already using DFS-R, and replication have been going on successfully; I can put a small 'canary' file on one of the RW DCs, and within minutes all the RODCs will have successfully replicated the 'canary' file.

  • Load balancing a Windows File Share using HA-Proxy

    - by NathanE
    After pulling my hair out over DFS I just had this weird and potentially dangerous idea come into my head whereby, just possibly, I might be able to use HA-Proxy to load balance a file share between servers. I've done some remedial packet traces and it does appear that TCP port 445 is the only thing involved in using Windows file sharing. I've always thought for many years that UDP 139, 135 etc were also involved in at least establishing the connection - but apparently not! So I setup a basic test: listen SMBTest *:445 mode tcp server Smb1 172.16.61.201:445 server Smb2 172.16.61.202:445 And you'll never guess what... it works??? (!) Now obviously there is the whole concern about synchronisation between the file servers (of course). That could easily be taken care of with a little bit of Robocopy script. And considering I only need a HA read-only file share there wouldn't be any issues with regard to file locking etc. Can anyone tell me if what I'm playing with here is fire? I really didn't think it would work at all and now I'm a little shocked. What would be the downsides? Could this be relied upon for a production environment?

  • What can cause Powershell execution policy not to be taken into account?

    - by Stephane
    We have in our infrastructure a number of powershell scripts used for various tasks ranging from user login to support technician simulating a user context. These scripts are centralized on our file server (through DFS) for easier management. Some of them are run at logon, some are run through published Citrix applications. We have applied a policy for the whole domain and all users that sets the Powershell execution policy to "unrestricted" so that the scripts can run from the file server. This works perfectly fine for logon script (at least, so far) but for scripts that are run later (usually through a published application but the same applies when using terminal services and a full desktop), the results are inconsistent: some users can run the script fine, some are always prompted in the powershell console for letting the scripts run. I cannot find anything that could cause this behavior and it's really inconsistent: if I start powershell manually and runs get-executionpolicy, I am told that the current policy is unrestricted. Yet, if from the same session I try to run a script through a program that calls powershell <script file name> <parameters> I get prompted before the script can run. What could cause such behavior ?

  • RRAS Problem routing to central site from RRAS server only?

    - by TomTom
    Given is an office connected to headquarters using a RRAS bridge (2 virtual machines using RRAS to route between the two networks). Naming: The office is A, the RRAS on A is a-lnk. THe headquartters is B, b-lnk the RRAS machine there. The VPN works perfectly - machines can ping and work between the sites. Domain controllers on both ends replicating, DFS working, remote desktop working. All in all... everything is fine. EXCEPT: a-lnk itself can not reach any machine in B. This would normally not be troublesome (noone ever does anything on a-lnk), but there are two exceptions: * a-lnk is supposed to get it's license from a KMS in B, so not being able to reach B means it is not prolonging. * a-lnk is supposed to pull updates from a WSUS in B - and not being able to reach B means - no updates. Given that thigns work (and security is a minor issue - A-lnk is not reachable from the internet as it is behing a NAT hardware anyway) this got not handled for months. I just wan to get this item ticked off now. Anyone an idea what this is? It definitely is not a "dns does not work" or "routing in general is bad" item, as any computer in A can connect to any computer in B, and the other way arount - only the RRAS computer itself seems to do something really awkward. Platform for both: 2008 R2 standard.

  • Why is it bad to map network drives in Windows?

    - by Beeblebrox
    There has been some spirited discussion within our IT department about mapping network drives. In particular, it has been said that mapping network drives is A Bad Thing and that adding DFS paths or network shares to your (Windows Explorer/Libraries) Favourites is a far better solution. Why is this the case? Personally I find the convenience of z:\folder to be better than \\server\path\folder', particularly with cmd line and scripting (of course I'm not talking about hard-coded links, naturally!). I have tried searching for pros and cons of mapped network drives, but I haven't seen anything other than 'should the network go down, the drive will be unavailable'. But this is a limitation of any network-accessed storage... I have also been told that mapped network drives poll the network when the network resource is unavailable, however I haven't found more information on this. Wouldn't this still be an issue with other network access mechanisms (that is, mapped Favourites) whenever Windows tries to enumerate the file system (for example, when a file/folder picker dialog is opened)? -- Do network drives poll the network any more than a Windows Explorer library/favourite?

  • EventID 1058 Code 5, Sysvol is subdir of Sysvol - how to fix?

    - by nulliusinverba
    I have been trying to resolve this error, like many others: The processing of Group Policy failed. Windows attempted to read the file \domain.local\SysVol\domain.local\Policies{3EF90CE1-6908-44EC-A750-F0BA70548600}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: a) Name Resolution/Network Connectivity to the current domain controller. b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). c) The Distributed File System (DFS) client has been disabled. Error code: 5 = Access Denied. The incredibly helpful post is this one (http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/A_1073-Diagnosing-and-repairing-Events-1030-and-1058.html). Quoting from this post: HERE IS A LIST OF POTENTIAL PROBLEMS THAT CAN LEAD TO 1030 AND 1058 EVENT ERRORS: --Sometimes the permissions of the file folders that contain Group policies (the Sysvol folder) can be corrupted. --Sometimes you have problems with NetBIOS: --Sometimes the GPO itself is corrupt, or you have a partial set of data for that GPO. --Sometimes you may have problems with File Replication Services, which almost always indicates a problem with DNS --Sysvol may be a subfolder of itself: Sysvol/Sysvol I have the problem listed where sysvol is a subfolder of sysvol. The directory structure is: -sysvol -domain -staging -staging areas -sysvol (shared as "\\server\sysvol") -domain.local -ClientAgent -Policies -scripts Interestingly, the second sysvol folder is the one that is shared as "\server\sysvol". This makes me confident this is the issue with the permissions and error code 5. Also interestingly, my server 2008 R2 servers can see it fine - my server 2008 servers cannot, and get the error. This is consistent across all my servers. This latter fact makes me uncertain what I need to do to fix this up. Do I, e.g., simply move the shared sysvol folder up a level to replace the non-shared one? Any help greatly appreciated. Cheers, Tim.

  • Network connection keeps dropping - bad hardware?

    - by Bill Sambrone
    Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

  • Shared Files stuck locked even after closing all sessions

    - by Chris S
    We run a business app from a shared network drive (has to be this way). When I go to do updates it complains that files are locked. Generally there are open sessions from people who left their computer on, but with no locks on files; there aren't necessarily always sessions open when it complains about locked files. If I close these sessions they disappear. I say "disappear" because I suspect they're actually hanging open. If I try to restart the Server service, it hangs on stopping. Restarting the whole server (it's a VM) unlocks the files. The Server is a Windows 2008 R2 Ent VM running on Hyper-V; the share is accessed through DFS. Offline Files and caching are disabled (Share and GPO). All clients are Win7. Nothing has SP1 yet. Any ideas on what causes the file locks to hang? Any ideas for a solution other than rebooting the server every time?

  • Does Active Directory on Server 2003 R2 support IPv6 subnets in Sites and Services?

    - by NorbyTheGeek
    I've been experimenting with IPv6 at our organization. The domain controllers (all 2003 R2) and most of the servers (2003 R2 / 2008 / 2008 R2) have IPv6 configured. We have a subnet assigned through a tunnel provider. Currently, the only workstation that is running IPv6 is mine. (Windows 7) I have been noticing that my workstation is picking domain controllers in other sites for things like DFS, and I finally realized that I don't have the IPv6 subnets set up in Active Directory Sites and Services (ADSS). But when I try to add a IPv6 prefix in ADSS, it tells me: Windows cannot create the object 2001:xxxx:xxxx:xxxx::/64 because: The object name has bad syntax. I believe I may be using the 2008 version of the admin tools (ADSS reports version 6.1.7601.17514) so I'm wondering if maybe my 2003 R2 Active Directory schema doesn't support configuring IPv6 subnets in ADSS. Is this true? UPDATE Even with 2008 R2 schema in Active Directory, I'm having the same problem. How can I get my IPv6 subnets into Sites and Services?

  • Expanding iSCSI LUNs (NTFS)

    - by Fatih
    I have a 4TB iSCSI LUN that formated as NTFS in Windows 2008. I've shared this formated volume as a folder over SMB. When the capacity of this volume is not enough, I have to add more iSCSI LUNs, but the end-users must see only the folder that I've shared before. So, when I expand the NTFS volume that is currently 4TB, with more iSCSI LUNS(for example 2 more 4TB LUN), if one of the luns is failed, or missing, will all of my data in the folder be lost? I imagine that the expanding ntfs volume is like RAID 0(striped). if it is like RAID 0, then all my data will be lost when one of the luns is failed, or missing. In brief, there are two questions in here: 1- What will be happened, if one of the luns is missing in an expanded ntfs volume? 2- Is there another way to merge all of iscsi luns as only a folder, in that way the users don't see any extra folder even if I add extra iscsi luns to the file server.(I don't mention about DFS) Regards.

  • Server 2008 email on Event variables

    - by Jeff Miles
    One of the new features of Server 2008 is the ability to attach a task to a specific event in the event logs. One of the actions available is to send an email through a SMTP server. This is working great, however it would be ideal if in the message body, the Event contents could be placed. I have tried using $eventdescription and %eventdescription%, but those are just shots in the dark. Any amount of googling produces no results. Does anyone know if this is possible?

  • Server 2008 email on Event variables

    - by Jeff Miles
    One of the new features of Server 2008 is the ability to attach a task to a specific event in the event logs. One of the actions available is to send an email through a SMTP server. This is working great, however it would be ideal if in the message body, the Event contents could be placed. I have tried using $eventdescription and %eventdescription%, but those are just shots in the dark. Any amount of googling produces no results. Does anyone know if this is possible? Update: Sparks' suggestion below is a step in the right direction I believe, however that method doesn't seem to work for all values.

  • After RAID failure SBS 2008 issues logging in and Exchange store does not mount

    - by Josh R
    today has been one of those days. Yesterday a hard drive in our Dell Poweredge 2900 server failed and the RAID array didn't degrade gracefully, so I called Dell (Server still under warranty) and got an engineer to work though the RAID issues with me. He was a nice guy but didn't do too much. We tried to put the RAID in a state where it was bootable and even though we only lost one disk there are still issues with the server. Once we got the server to boot there was an error message saying that the logonui.exe was corrupted and we needed to run chkdsk. I clicked through the error messages and the login screen never came up. So I power cycled the server and it chkdsk automatically but the login screen didn't appear. I tried safe mode, no difference there either. So the issues I am currently having are: 1) The server boots up, the loading windows screen comes up then it dumps me into a black screen where I can only see my mouse cursor. Ctrl+Esc doesn't work Ctrl+Alt+Del doesn't work 2) Some of the services come up: DHCP, DNS, DFS, and Print come up 3) The exchange information store and transport service don't start - I tried using mmc to connect to services.msc on the computer and start them but they throw an error message of "Can't start because group or dependency failed" Has anyone had a problem like this? Can anyone offer some guidance? Thanks a bunch!

  • Server 2012 - transparent SMB failover without shared discs, possible?

    - by TomTom
    here is the scenario - there is a small set (200gb around) of data that I HAVE to keep available. Those are basically shared VHD images that serve as master images for a lot of our VM's - they then run in differential discs off those. The whole set is "mostly read only". In more detail: A file that IS there and IS used will NEVER change. I may delete files (when absolutely not in use) and add new files, but a file that is there once gets read protection set and that it is until it is retired. Obviously, I need as much uptime as possible. SO FAR we run that by having this directory local on every Hyper-V server. Now I think moving this into our storage fabric. Due to the "it HAS to be there" I pretty much want a share nothing architecture. DFS would be perfect for this - a file never changes, so replication would work nicely. Folders could be replicated to a number of servers, all would reference them from there. Now, that hyper-V supports SMB that could be a good idea to isolate these on a number of servers - we try to move into a scenario where the storage is more centralized. Server 2012 supports always on shares, but it seems that this only works with a clustered disc behind. Is there any way around this for read only file stores? All documentation points to stuff like a shared JBOD - but that would leave me open for file system corruption. I really plan to go quite separately here, vertically - 2 servers, both with SSD only for this, both with their own 2000W separate USV, both with enough bandwidth to handle everything thrown at them (note to everyone tinking this is 10G - this would be SLOW and EXPENSIVE compared to a nice Infiniband backbone). The real crux is that this is an edge case obviously - as the files are read only once in use.

  • Fastest pathfinding for static node matrix

    - by Sean Martin
    I'm programming a route finding routine in VB.NET for an online game I play, and I'm searching for the fastest route finding algorithm for my map type. The game takes place in space, with thousands of solar systems connected by jump gates. The game devs have provided a DB dump containing a list of every system and the systems it can jump to. The map isn't quite a node tree, since some branches can jump to other branches - more of a matrix. What I need is a fast pathfinding algorithm. I have already implemented an A* routine and a Dijkstra's, both find the best path but are too slow for my purposes - a search that considers about 5000 nodes takes over 20 seconds to compute. A similar program on a website can do the same search in less than a second. This website claims to use D*, which I have looked into. That algorithm seems more appropriate for dynamic maps rather than one that does not change - unless I misunderstand it's premise. So is there something faster I can use for a map that is not your typical tile/polygon base? GBFS? Perhaps a DFS? Or have I likely got some problem with my A* - maybe poorly chosen heuristics or movement cost? Currently my movement cost is the length of the jump (the DB dump has solar system coordinates as well), and the heuristic is a quick euclidean calculation from the node to the goal. In case anyone has some optimizations for my A*, here is the routine that consumes about 60% of my processing time, according to my profiler. The coordinateData table contains a list of every system's coordinates, and neighborNode.distance is the distance of the jump. Private Function findDistance(ByVal startSystem As Integer, ByVal endSystem As Integer) As Integer 'hCount += 1 'If hCount Mod 0 = 0 Then 'Return hCache 'End If 'Initialize variables to be filled Dim x1, x2, y1, y2, z1, z2 As Integer 'LINQ queries for solar system data Dim systemFromData = From result In jumpDataDB.coordinateDatas Where result.systemId = startSystem Select result.x, result.y, result.z Dim systemToData = From result In jumpDataDB.coordinateDatas Where result.systemId = endSystem Select result.x, result.y, result.z 'LINQ execute 'Fill variables with solar system data for from and to system For Each solarSystem In systemFromData x1 = (solarSystem.x) y1 = (solarSystem.y) z1 = (solarSystem.z) Next For Each solarSystem In systemToData x2 = (solarSystem.x) y2 = (solarSystem.y) z2 = (solarSystem.z) Next Dim x3 = Math.Abs(x1 - x2) Dim y3 = Math.Abs(y1 - y2) Dim z3 = Math.Abs(z1 - z2) 'Calculate distance and round 'Dim distance = Math.Round(Math.Sqrt(Math.Abs((x1 - x2) ^ 2) + Math.Abs((y1 - y2) ^ 2) + Math.Abs((z1 - z2) ^ 2))) Dim distance = firstConstant * Math.Min(secondConstant * (x3 + y3 + z3), Math.Max(x3, Math.Max(y3, z3))) 'Dim distance = Math.Abs(x1 - x2) + Math.Abs(z1 - z2) + Math.Abs(y1 - y2) 'hCache = distance Return distance End Function And the main loop, the other 30% 'Begin search While openList.Count() != 0 'Set current system and move node to closed currentNode = lowestF() move(currentNode.id) For Each neighborNode In neighborNodes If Not onList(neighborNode.toSystem, 0) Then If Not onList(neighborNode.toSystem, 1) Then Dim newNode As New nodeData() newNode.id = neighborNode.toSystem newNode.parent = currentNode.id newNode.g = currentNode.g + neighborNode.distance newNode.h = findDistance(newNode.id, endSystem) newNode.f = newNode.g + newNode.h newNode.security = neighborNode.security openList.Add(newNode) shortOpenList(OLindex) = newNode.id OLindex += 1 Else Dim proposedG As Integer = currentNode.g + neighborNode.distance If proposedG < gValue(neighborNode.toSystem) Then changeParent(neighborNode.toSystem, currentNode.id, proposedG) End If End If End If Next 'Check to see if done If currentNode.id = endSystem Then Exit While End If End While If clarification is needed on my spaghetti code, I'll try to explain.

  • Why is my logic not working correctly for SPOJ TOPOSORT?

    - by Kavish Dwivedi
    The given problem is http://www.spoj.com/problems/TOPOSORT/ The output format is particularly important as : Print "Sandro fails." if Sandro cannot complete all his duties on the list. If there is a solution print the correct ordering, the jobs to be done separated by a whitespace. If there are multiple solutions print the one, whose first number is smallest, if there are still multiple solutions, print the one whose second number is smallest, and so on. What I am doing is simply doing dfs by reversing the edges i.e if job A finishes before job B, there is a directed edge from B to A . I am maintaining the order by sorting the adjacency list I created and storing the nodes which don't have any constraints separately so as to print them later in correct order . There are two flag arrays used , one for marking discovered node and one for marking the node whose all neighbors have been explored. Now my solution is http://www.ideone.com/QCUmKY (the important function is the visit funtion ) and its giving WA after running correct for 10 cases so its really hard to figure out where am I doing it wrong since it runs for all of the test cases which I have done by hand.

  • Hadoop reduce task gets hung

    - by user806098
    I set up a hadoop cluster with 4 nodes, When running a map-reduce task, the map task finishes quickly, while the reduce task hangs at 27% percent. I checked the log, it's that the reduce task fails to fetch map output from map nodes. The job tracker log of master shows messages like this: 2011-06-27 19:55:14,748 INFO org.apache.hadoop.mapred.JobTracker: Adding task (REDUCE) 'attempt_201106271953_0001_r_000000_0' to tip task_201106271953_0001_r_000000, for tracker 'tracker_web30.bbn.com.cn:localhost/127.0.0.1:56476' And the name node log of master shows messages like this: 2011-06-27 14:00:52,898 INFO org.apache.hadoop.ipc.Server: IPC Server handler 4 on 54310, call register(DatanodeRegistration(202.106.199.39:50010, storageID=DS-1989397900-202.106.199.39-50010-1308723051262, infoPort=50075, ipcPort=50020)) from 192.168.225.19:16129: error: java.io.IOException: verifyNodeRegistration: unknown datanode 202.106.199.3 9:50010 However, neither the "web30.bbn.com.cn" or 202.106.199.39, 202.106.199.3 is the slave node. I think such ip/domains appear because hadoop fails to resolve a node(first in the Intranet DNS server), then it goes to a higher-level DNS server, later to the top, still fails, then the "junk" ip/domains are returned. But I checked my config, it goes like this: /etc/hosts: 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 192.168.225.16 master 192.168.225.66 slave1 192.168.225.20 slave5 192.168.225.17 slave17 conf/core-site.xml: hadoop.tmp.dir /root/hadoop_tmp/hadoop_${user.name} fs.default.name hdfs://master:54310 io.sort.mb 1024 hdfs-site.xml: dfs.replication 3 masters: master slaves: master slave1 slave5 slave17 Also, all firewalls(iptables) are turned off, and ssh between each 2 nodes is ok. so I don't know where exact the error comes from. Please help. Thanks a lot.

  • Sharing storage between servers

    - by El Yobo
    I have a PHP based web application which is currently only using one webserver but will shortly be scaling up to another. In most regards this is pretty straightforward, but the application also stores a lot of files on the filesystem. It seems that there are many approaches to sharing the files between the two servers, from the very simple to the reasonably complex. These are the options that I'm aware of Simple network storage NFS SMB/CIFS Clustered filesystems Lustre GFS/GFS2 GlusterFS Hadoop DFS MogileFS What I want is for a file uploaded via one webserver be immediately available if accessed through the other. The data is extremely important and absolutely cannot be lost, so whatever is implemented needs to a) never lose data and b) have very high availability (as good as, or better, than a local filesystem). It seems like the clustered filesystems will also provide faster data access than local storage (for large files) but that isn't of vita importance at the moment. What would you recommend? Do you have any suggestions to add or anything specifically to look out for with the above options? Any suggestions on how to manage backup of data on the clustered filesystems?

  • ArrayList<String> NullPointerException

    - by Carlucho
    Am trying to solve a labyrinth by DFS, using adj List to represent the vertices and edges of the graph. In total there are 12 nodes (3 rows[A,B,C] * 4 cols[0,..,3]). My program starts by saving all the vertex labels (A0,..C3), so far so good, then checks the adjacent nodes, also no problems, if movement is possible, it proceeds to create the edge, here its where al goes wrong. adjList[i].add(vList[j].label); I used the debugger and found that vList[j].label is not null it contains a correct string (ie. "B1"). The only variables which show null are in adjList[i], which leads me to believe i have implemented it wrongly. this is how i did it. public class GraphList { private ArrayList<String>[] adjList; ... public GraphList(int vertexcount) { adjList = (ArrayList<String>[]) new ArrayList[vertexCount]; ... } ... public void addEdge(int i, int j) { adjList[i].add(vList[j].label); //NULLPOINTEREXCEPTION HERE } ... } I will really appreaciate if anyone can point me on the right track regrading to what its going wrong... Thanks!

  • Grails - ElasticSearch - QueryParsingException[[index] No query registered for [query]]; with elasticSearchHelper; JSON via curl works fine though

    - by v1p
    I have been working on a Grails project, clubbed with ElasticSearch ( v 20.6 ), with a custom build of elasticsearch-grails-plugin(to support geo_point indexing : v.20.6) have been trying to do a filtered Search, while using script_fields (to calculate distance). Following is Closure & the generated JSON from the GXContentBuilder : Closure records = Domain.search(searchType:'dfs_query_and_fetch'){ query { filtered = { query = { if(queryTxt){ query_string(query: queryTxt) }else{ match_all {} } } filter = { geo_distance = { distance = "${userDistance}km" "location"{ lat = latlon[0]?:0.00 lon = latlon[1]?:0.00 } } } } } script_fields = { distance = { script = "doc['location'].arcDistanceInKm($latlon)" } } fields = ["_source"] } GXContentBuilder generated query JSON : { "query": { "filtered": { "query": { "match_all": {} }, "filter": { "geo_distance": { "distance": "5km", "location": { "lat": "37.752258", "lon": "-121.949886" } } } } }, "script_fields": { "distance": { "script": "doc['location'].arcDistanceInKm(37.752258, -121.949886)" } }, "fields": ["_source"] } The JSON query, using curl-way, works perfectly fine. But when I try to execute it from Groovy Code, I mean with this : elasticSearchHelper.withElasticSearch { Client client -> def response = client.search(request).actionGet() } It throws following error : Failed to execute phase [dfs], total failure; shardFailures {[1][index][3]: SearchParseException[[index][3]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query_binary":"eyJxdWVyeSI6eyJmaWx0ZXJlZCI6eyJxdWVyeSI6eyJtYXRjaF9hbGwiOnt9fSwiZmlsdGVyIjp7Imdlb19kaXN0YW5jZSI6eyJkaXN0YW5jZSI6IjVrbSIsImNvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiI6eyJsYXQiOiIzNy43NTIyNTgiLCJsb24iOiItMTIxLjk0OTg4NiJ9fX19fSwic2NyaXB0X2ZpZWxkcyI6eyJkaXN0YW5jZSI6eyJzY3JpcHQiOiJkb2NbJ2NvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiddLmFyY0Rpc3RhbmNlSW5LbSgzNy43NTIyNTgsIC0xMjEuOTQ5ODg2KSJ9fSwiZmllbGRzIjpbIl9zb3VyY2UiXX0=","explain":true}]]]; nested: QueryParsingException[[index] No query registered for [query]]; } The above Closure works if I only use filtered = { ... } script_fields = { ... } but it doesn't return the calculated distance.

  • How to perform a Depth First Search iteratively using async/parallel processing?

    - by Prabhu
    Here is a method that does a DFS search and returns a list of all items given a top level item id. How could I modify this to take advantage of parallel processing? Currently, the call to get the sub items is made one by one for each item in the stack. It would be nice if I could get the sub items for multiple items in the stack at the same time, and populate my return list faster. How could I do this (either using async/await or TPL, or anything else) in a thread safe manner? private async Task<IList<Item>> GetItemsAsync(string topItemId) { var items = new List<Item>(); var topItem = await GetItemAsync(topItemId); Stack<Item> stack = new Stack<Item>(); stack.Push(topItem); while (stack.Count > 0) { var item = stack.Pop(); items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } } return items; } EDIT: I was thinking of something along these lines, but it's not coming together: var tasks = stack.Select(async item => { items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } }).ToList(); if (tasks.Any()) await Task.WhenAll(tasks); UPDATE: If I wanted to chunk the tasks, would something like this work? foreach (var batch in items.BatchesOf(100)) { var tasks = batch.Select(async item => { await DoSomething(item); }).ToList(); if (tasks.Any()) { await Task.WhenAll(tasks); } } The language I'm using is C#.

  • JAVA - How to code Node neighbours in a Grid ?

    - by ke3pup
    Hi guys I'm new to programming and as a School task i need to implement BFS,DFS and A* search algorithms in java to search for a given Goal from a given start position in a Grid of given size, 4x4,8x8..etc to begin with i don't know how to code the neighbors of all the nodes. For example tile 1 in grid as 2 and 9 as neighbors and Tile 12 has ,141,13,20 as its neighbours but i'm struggling to code that. I need the neighbours part so that i can move from start position to other parts of gird legally by moving horizontally or vertically through the neighbours. my node class is: class node { int value; LinkedList neighbors; bool expanded; } let's say i'm given a 8x8 grid right, So if i start the program with a grid of size 8x8 right : 1 - my main will func will create an arrayList of nodes for example node ArrayList test = new ArrayList(); and then using a for loop assign value to all the nodes in arrayList from 1 to 64 (if the grid size was 8x8). BUT somehow i need t on coding that, if anyone can give me some details i would really appreciate it.
