Hi Chandraprakash,

Yes node22 is I have not entered a corresponding entry, in any of the machines,on /etc/hosts (right now, I don't have the access privileges to do that, hoping to get that soon). I am able to ssh from node22 (the master) to nodes 20,21 and 23 (the slaves) without a password and also from the slaves to the master.

Thanks for your help,

I am trying to setup a cluster with 4 nodes and I followed all the steps
listed here:

just one (which I am assuming is the master node) and when I checked the
logs on the datanode, I am getting this message: " Retrying connect to
server: node22/ Already tried 9 time(s).
2009-09-14 17:31:50,934 INFO org.apache.hadoop.ipc.RPC: Server at node22/ not available yet, Zzzzz...". I am not able to
proceed from here, any help on finding the leads is appreciated.
