>                 URL: https://issues.apache.org/jira/browse/HBASE-10626
>             Project: HBase
>          Issue Type: Bug
>          Components: master
>    Affects Versions: 0.96.1.1
>         Environment: hadoop-2.2.0
>            Reporter: xinrong
>            Priority: Trivial
>
> since the hadoop-2.2.0 need a reverse look up about hostname and our dns doesn't support
the reverse look up,  we configured the "/etc/hosts" of namenode, This lead a bug when we
started hbase master in the same machine of namenode:
> the "HMaster" would get a "ServerName" which consisted of hostname,port,ts and get another
"ServerName" from zookeeper consisted of ip,port,ts, One regionserver will be recorded twice.
