dhruba borthakur commented on HADOOP-2891:
------------------------------------------
The bug is demonstrated by unit test failure in TestMiniMRDFSSort, no separate
unit test necessary. Regarding the findbugs warning, "findbugs" in able to
detect that one thread is closed() and joined() before the "streamer" variable
is accessed, thus it is safe and is not a bug.
> The dfsclient on exit deletes files that are open and not closed.
