Subject Re: Slaves are not able to connect to master

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,

named <> as node22 in /etc/hosts?

datanodes without password?
