Examples of org.apache.hadoop.hbase.MasterProtocol

org.apache.hadoop.hbase.MasterProtocol
Functions implemented by all the master protocols: e.g. {@link MasterAdminProtocol}and {@link MasterMonitorProtocol}. Currently, the only shared method {@link #isMasterRunning(com.google.protobuf.RpcController,org.apache.hadoop.hbase.protobuf.generated.MasterProtos.IsMasterRunningRequest)}which is used on connection setup to check if the master has been stopped.

        MasterProtocol tryMaster = rpcEngine.getProxy(
            masterProtocolState.protocolClass,
            isa, this.conf, this.rpcTimeout);

          LOG.info(msg);
