Hi,
I have 3 nodes cluster. Each hostname resolve to IP correctly . Each machine is
able to ping each other as well as passwordless SSH is also working fine.
I wanted to start regionserver on all 3 machines so I updated conf/regionserver
file with hostname of different machine.
Firewall is off in each machine.
Cluster Config:
Master Machine : master
Slave Machine : slave
slave2
When Hbase master try to start daemons on slave2 machine, it shows up error and
then shuts down :
Error :

Any pointers will be good.
