FAQ
Hi Chandraprakash,

Yes node22 is 128.226.118.98. 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,
Arun

named 128.226.118.98 <http://128.226.118.98:54310/> as node22 in /etc/hosts?

All,

I am trying to setup a cluster with 4 nodes and I followed all the steps
listed here:
http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_(Multi-Node_Cluster)<http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_%28Multi-Node_Cluster%29>except the /etc/hosts step. But for some reason the number of datanodes is
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: node22/128.226.118.98:54310. Already tried 9 time(s).
2009-09-14 17:31:50,934 INFO org.apache.hadoop.ipc.RPC: Server at node22/
128.226.118.98:54310 not available yet, Zzzzz...". I am not able to
proceed from here, any help on finding the leads is appreciated.

Thanks,
Arun
