Jitendra Nath Pandey commented on HADOOP-7661:
----------------------------------------------

It seems to me that this issue (and also HADOOP-7602) got introduced in MAPREDUCE-2780. I would prefer that the trunk patch for that jira, doesn't introduce this issue or the issue in HADOOP-7602. We should port the tests though.
