Jonathan Hung created MAPREDUCE-6885:
----------------------------------------
Summary: JobHistory event handler thread should not die if
exception thrown
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.
