hdfs configuration
- by Ananymous
I am a newbie. Trying to setup a hdfs system to serve my data (I don't plan to use mapreduce) at my lab.
So far I have read, cluster setup in but I am still confused.
Several questions:
Do I need to have a secondary namenode?
There are 2 files, masters and
slaves. Do I really need these 2
files eventhough I just want hdfs? If
I need them, what should go in there?
I assume my namenode in masters and
datanodes as slaves? Do I need slaves nodes
What configuration files are needed
for namenode, secondary namenode,
datanode and client? (I assume
core-site.xml is needed for all 4)? In addition, can someone suggest a good
configuration model? sample
configuration for namenode, secondary
namenode, datanode, and the client would be very helpful.
I am getting confused because it seems most of the documentation assumes I want to use map-reduce which isn't the case.
