Robert Joseph Evans commented on MAPREDUCE-4901:
------------------------------------------------
[~mitdesai],
I really don't have a lot of time to devote to this right now. If you are
willing to wait I can try to take a look at upmerging, but it would probably be
faster for someone else to take it if it is important to them.
> JobHistoryEventHandler errors should be fatal

> Key: MAPREDUCE-4901
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4901
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0, 2.0.0-alpha
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans

> To be able to truly fix issues like MAPREDUCE-4819 and MAPREDUCE-4832, we
> need a 2 phase commit where a subsequent AM can be sure that at a specific
> point in time it knows exactly if any tasks/jobs are committing. The job
> history log is already used for similar functionality so we would like to
> reuse this, but we need to be sure that errors while writing out to the job
> history log are now fatal.
