[jira] [Created] (HBASE-11669) The HMaster uses the same port with HRegionServer

Jingcheng Du created HBASE-11669:
------------------------------------

             Summary: The HMaster uses the same port with HRegionServer
                 Key: HBASE-11669
                 URL: https://issues.apache.org/jira/browse/HBASE-11669
             Project: HBase
          Issue Type: Bug
          Components: master, regionserver
    Affects Versions: 0.99.0
            Reporter: Jingcheng Du
            Priority: Blocker


HMaster uses the same port with the HRegionServer.
In the constructor of HMaster, it has to run super(conf, csm) which is HRegionServer. In this method, the rpc service is instantiated, and HMaster and HRegionServer will use the same rpc configuration. If users start the HMaster and HRegionServer in the same server, the error "Address already in use" occurs when HRegionServer starts up.
