Alejandro Abdelnur commented on OOZIE-835:
------------------------------------------
Instead using a shutdownhook, we should use a monitor thread that detects that
no testcase is running for X seconds and then triggers a shutdown of the
minicluster
> XTestCase Minicluster hangs when shutting down with an exception using Hadoop
> 2
