Siddharth Seth updated MAPREDUCE-3463:
--------------------------------------

    Attachment: MR3463_v2.txt

TestRecovery was faling silently without the previous patch (System.exit in the dispatcher).

This patch changes the test to cause a unit test failure if the dispatcher catches an exception.
