Sharad Agarwal commented on MAPREDUCE-3489:
-------------------------------------------

Definately System.exit is not the right thing in a library. Sigh! I knew that when I wrote that and intended to remove it. Couldn't get chance to get to it. 
I think we should get rid of it and instead have a error handling callback registered to Dispatcher.

> 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.
