All core and contrib tests passed.

The problem with the failing streaming test cases was 
# contrib test doesnt respect src/test/mapred-site.xml
# streaming testcase expect the build/contrib/streaming/test/data/ folder to have empty *out*
folder.  Fixed the tests to not create _SUCCESS.

> The OutputCommitter needs an abortJob method to clean up from failed jobs. Currently
there is no way to distinguish between failed or succeeded jobs, making it impossible to write
output promotion code.
