Vinod Kumar Vavilapalli commented on MAPREDUCE-3040:
----------------------------------------------------

I merged this into branch-0.23.

I was surprised why we didn't see these failures before, and as it turns out, the patch builds aren't running any of these tests. These tests need the MRApp jar, which isn't generated if we only do "mvn test" like the patch builds. Will fix the test-patch script to run "mvn clean install test" for tests.
