Subject [jira] [Commented] (MAPREDUCE-3489) EventDispatcher should have a call-back on errors for aiding tests
Date Fri, 27 Jan 2012 21:17:09 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195103#comment-13195103

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.

> 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.
