Subject: Hbase : Failed setting up proxy interface

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

When Hbase master try to start daemons on slave2 machine, it shows up error and then shuts
down :

Error :

>From the logs it shows that its proxy issue , but since the slave2  is in same network
as with slave, master Im not sure why it is happening.

Any pointers will be good.
