Eric Payne updated HDFS-7533:
-----------------------------
Status: Patch Available (was: Open)
> Datanode sometimes does not shutdown on receiving upgrade shutdown command
> --------------------------------------------------------------------------
>
> Key: HDFS-7533
> URL: https://issues.apache.org/jira/browse/HDFS-7533
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Kihwal Lee
> Assignee: Eric Payne
> Attachments: HDFS-7533.v1.txt
>
>
> 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.
