Harsh J updated MAPREDUCE-2623:
-------------------------------

    Attachment: MAPREDUCE-2623.r1.diff

(Saw it was unassigned, so picked it up!)

This should cover the change. I ran {{TestJobName}}, which uses it, and it succeeded. Lets
see if QA says the sameā€¦

> Looking at test class ClusterMapReduceTestCase it issues a warning that the dfsCluster
= new MiniDFSCluster(conf, 2, reformatDFS, null); line of code is deprecated and MiniDFSCluster.Builder
should be used instead. It notes that the current API will be phased out in version 24. I
propose to update the test class to the most up to date code as it's referenced several places
on the internet as an example of how to write a Hadoop Unit Test.
