Suhas Gogate commented on HADOOP-5950:
--------------------------------------

Failed tests are not related to this patch or vaidya contrib project. So can someone pl. commit
the patch as I would like to add a patch for some new rules. Thanks!

> some of the existing rules fail with divide by zero or arithmetic exception as map only
jobs do not log reduce side counters. Vaidya driver code and Rules need to be modified to
take care of such jobs.
