Thank you Harsh & Shashwat I given the hostname in /etc/sysconfig/network as pseudo-distributed. hostname command returns this name also. I added this name in /etc/hosts file and changed all the configuration accordingly. But zookeeper is trying to resolve to localhost.localdomain. There was no entries in any conf files or hostname related files for localhost.localdomain.
Yea, everything is pinging as I given the names in /etc/hosts.
