Vinod Kumar Vavilapalli reopened HDFS-6040:
-------------------------------------------


I think this is the patch that has broken many tests in MapReduce and also resulted in a RAT warning. Please see the last comment by Jenkins at YARN-986. Test results: https://builds.apache.org/job/PreCommit-YARN-Build/3237//testReport/ and Release audit warnings: https://builds.apache.org/job/PreCommit-YARN-Build/3237//artifact/trunk/patchprocess/patchReleaseAuditProblems.txt

Reopening this. Please let me know if this is not the culpable ticket..
