Bharat Viswanadham commented on HADOOP-14857:
---------------------------------------------

[~busbey] Updated the patch, which resolved the issue.
Could you please review the changes.

But this warning is coming up during building
WARNING] hamcrest-core-1.3.jar, mockito-all-1.8.5.jar define 21 overlapping classes: 
[WARNING]   - org.hamcrest.internal.SelfDescribingValue

As mockitio packages hamcrest with it. Any idea, how to proceed with this?
