Re: HRegionserver daemon is not running on region server node

I suspect that the daemon's are binding to 127.0.0.1 instead of
10.0.1.54 on the master. You can check this by running netstat -anp. I
would recommend either configuring the /etc/hosts to bind the
vamshikrishna-desktop and vamshi-laptop hostnames to the 10.0.1.x
addresses.
