  • can i use hadoop cloudera without root access?

    - by in_the_cloud
    a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)? appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial

  • Passwordless SSH using cgi-perl script

    - by AV
    Hello, This is my first shot at trying out cgi-perl scripts. I have SSH keys set up between my (root user) local machine and a remote machine. I'm trying to run a command on the remote box and display the output on a webpage hosted from my local machine. The script runs fine from command line however, it throws SSH key error when called from the webpage because the user running the script is apache and not root. Is there a way to get around this issue?

  • user specifc maven settings in repository

    - by Samuel
    http://maven.apache.org/settings.html As per documentation the user specific settings can be either copied to the .m2 folder or under the maven installation. If a developer changes a machine or gets a new user id, such properties have to be copied manually to these newer machines. Would it be possible to store user specific setting information in the repository itself (say SVN) and somehow have the mvn scripts load it on startup.

  • Best practice for managing changes to 3rd party open source libraries?

    - by Jeff Knecht
    On a recent project, I had to modify an open source library to address a functional deficiency. I followed the SVN best practice of creating a "vendor source" repository and made my changes there. I also submitted the patch to the mailing list of that project. Unfortunately, the project only has a couple of maintainers and they are very slow to commit updates. At some point, I expect the library to be updated, and I expect that my project will want to use the upgraded library. But now I have a potential problem... I don't know whether my patch will have been applied to this future release of the 3rd party library. I also don't know whether my patch will even still be compatible with the internal implementation of the upgraded components. And in all likelihood, someone else will be maintaining my project by that point. Should I name the library in a special way so it is clear that we made special modifications (eg. commons-lang-2.x-for-my-project.jar)? Should I just document the patch and reference the SVN location and a link to the mailing list item in a README? No option that I can think of seems to be fool-proof in an upgrade scenario. What is the best practice for this?

  • Sharing DefaultHttpClient in Android. To synchronize or not to synchronize?

    - by johnrock
    In an Android app, I am using one static instance of org.apache.http.impl.client.DefaultHttpClient and sharing that instance in all activities and services of the app, so that this client may be used to log in once to a remote server and all subsequent user requests to that remote server will remain authenticated. Every activity or Service that makes a GET or POST to this remote server calls the same method : MyUtilityClass.gettHttpClient() Do I need to worry about synchronization of this httpclient? If so, what is the best way to handle this?

  • How to delete Tomcat Access Log after n days?

    - by Andreas
    I only would like to keep the Access Logs of the last n days created by Tomcat Access Log Valve. http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access%20Log%20Valve But there seems to be no configuration-Attribute to define how long to keep the log-files? I guess this is because "Access Log Valve" only creates log files and doesn't delete them, is that correct?

    - by Sam
    Hi so I am trying to create a deb package for a web application written in Java (it uses Apache Tomcat). My eventual goal is to start a repository that people can add to apt-get the software, but How do I make it so that the package knows to look for dependencies like tomcat, sun-java6-bin, and ant?

  • Error when deploying site of a maven multi module project with FTP

    - by julien
    I have a multi module project. When I launch mvn site:deploy, the deployment of the base module works fine, but it fails to create the directory of the module sites on the FTP server: [INFO] Error uploading site Embedded error: Required directory: '/myremoteftprepository/myproject-mymodule' is missing When I create the missing directory by hand, it works fine, but I would like to avoid that. It is surprising that the deploy command do not create it. Do you how to force this directory creation? Is it a bug in the wagon-ftp plugin? FYI, here is my POM: <build> <extensions> <!-- Enabling the use of FTP --> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-ftp</artifactId> <version>1.0</version> </extension> </extensions> </build> I have chosen to include the javadoc with: <reporting> <plugins> <!-- include javadoc in the site --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.8</version> <configuration> <show>public</show> </configuration> </plugin> </plugins> </reporting> and <distributionManagement> <site> <id>site</id> <name>maven site</name> <url>ftp://ftp.blabla.org/myremoteftprepository</url> </site> </distributionManagement> and my settings.xml is good.

  • Questions about HTML5 audio

    - by Nimbuz
    <audio src="http://upload.wikimedia.org/wikipedia/commons/8/82/Riddle_song.ogg"></audio> <ul id="lyrics"> <li>line 1</li> <li>line 2</li> <li>line 3</li> <li>and so on...</li> </ul><!-- end #lyrics --> So I want to: Highlight (change color or background) of the line that is being played. Save current time to a cookie and resume on next visit. I'm not sure if either of these are possible in HTML5, but even in Flash or other technology, I'd like to know if and how it is possible. I understand #2 is asking too much, but #1 is really important. So almost similar to this: http://randallagordon.com/jaraoke/ but all the lines are visible, just the current line is highlighted. Many thanks for your help.
