      HMaster is not a sub class for HRegionServer now, and also MasterRpcServices is not a sub class for RSRpcServices.

      MasterRpcServices still implements the AdminService interface, but only updateConfiguration, getRegionInfo, clearSlowLogsResponses and getLogEntries can be called, for other methods in AdminService, you will get a DoNotRetryIOException when calling against master.
