Jonathan Hung updated MAPREDUCE-6885:
-------------------------------------
Summary: JobHistory event handling does not complete if handling event
throws exception on shutdown (was: JobHistory event handler thread should not
die if exception thrown)
> JobHistory event handling does not complete if handling event throws
> exception on shutdown
> ------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-6885
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6885
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Jonathan Hung
>
> If eventHandlingThread handles an event which causes it to throw an exception
> (e.g. if it is unable to flush an event to HDFS), the thread dies. This
> thread is responsible for moving job history files to
> mapreduce.jobhistory.done-dir, if an exception is thrown the files will not
> be moved here, which is bad.
> We should catch these exceptions so that the thread can still move these
> files when the job is complete.
