> Datanode sometimes does not shutdown on receiving upgrade shutdown command

>
> 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.
