Subject Re: Hbase 0.90.0 doesnt stop.

Hi Ted,

       After resetting the ZK Data. Now I have 6 more region servers. :-( .
It has to be mentioned though, after cleaning up , HBase took forever to
start.

       If you don't mind, Can you let me know the exact steps to verify if
reverse DNS is setup fine?

Thanks,
Charan
