Pseudo Distributed: ERROR org.apache.hadoop.hbase.HServerAddress:
Could not resolve the DNS name of localhost.localdomain
Hi All,
In pseudo distributed node HBaseMaster is stopping automatically when we
starts HbaseRegion.
I have changed all the configuration files of Hadoop,Hbase & Zookeeper to
set the exact hostname of the machine. Also commented the localhost entry
from /etc/hosts & cleared the cache as well. There is no entry of
localhost.localdomain entry in these configurations, but this it is
resolving to localhost.localdomain.
Please find the error:

This is pretty basic. Fix this first and then your hbase will work.
Please stop spraying your queries across multiple lists. Doing so
makes us think you arrogant which I am sure is not the case. Pick the
list that seems most appropriate. For example, in this case, it seems
like the hbase-user list would have been the right place to write; not
common-user and cdh-user. If it turns out you've chosen wrong,
usually the chosen list will help you figure the proper target.
Thanks,
St.Ack

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.

Hbase stops means its not able to start itself on the ip or hostname which
