> - This feature is very useful for unit testing map/reduce tasks, it would
> allow verifying an expected failure reason.
> - The class mapred.LocalJobRunner currently returns an empty
> TaskCompletionEvent array when requested for task completion events
> - In line 231 in LocalJobRunner.java a map/reduce exception is caught and
> *not* propagated to the user.
> - I would be useful to get the exception message through a
> TaskCompletionEvent or event or by any other means.
