Vinod Kumar Vavilapalli commented on MAPREDUCE-3489:
----------------------------------------------------
bq. Currently in the AsyncDispatcher, exitOnDispatchException defaults to
false. The daemon don't set it to true either.
That is done as part of MAPREDUCE-3634 which isn't committed yet. Appreciate a
quick review there ;)
You can develop your patch over MAPREDUCE-3634.
> EventDispatcher should have a call-back on errors for aiding tests

> Key: MAPREDUCE-3489
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3489
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Siddharth Seth
> Assignee: Sharad Agarwal
>
> If one of the dispatched events generates an exception - the dispatcher kills
> the JVM via a System.exit. Unit tests end up not running - but they don't
> fail either.
> TestTaskAttempt is currently running like this.
> Previously - have seen TestRecovery and TestJobHistoryParsing do the same.
> Most of the tests would need to be looked at.
