Thanks JD.
I will change the host names back to their original.

It's this bug: https://issues.apache.org/jira/browse/HBASE-3478
I can't think of any easy workaround at the moment except than
creating new DNS entries with the old hostnames...

Sorry.
Clicked send too early.
We recently changed the hostnames of the Hbase installation. Including
region servers and master node. After adjusting and clearing the zookeeper,
HBase master doesnt start.
It still has some reference to the old hostnames. I am suspecting in
.META.

Any advice.
