Datanode sometimes does not shutdown on receiving upgrade shutdown command

      Description

      When datanode is told to shutdown via the dfsadmin command during rolling upgrade, it may not shutdown. This is because not all writers have responder running, but sendOOB() tries anyway. This causes NPE and the shutdown thread dies, halting the shutdown after only shutting down DataXceiverServer.
