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. -- This message was sent by Atlassian JIRA (v6.2#6252)
