xinrong created HBASE-10626:
-------------------------------

             Summary: master receives servernames from zk and rs, It happend when master get
different hostname with same IP
                 Key: HBASE-10626
                 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.
