-----------------------------------------------

             Summary: FileOutputCommitter.abortTask should check a result of outputFileSystem.delete(workPath, true);
                 Key: MAPREDUCE-4945
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4945
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.21.0, 0.20.205.0
            Reporter: Oleksandr Alesinskyy


MAPREDUCE-1409 partially fixes a problem with an retained output of aborted tasks - unfortunately, the fix is incomplete, there are cases when a {{delete()}} method does neither deletes a file nor throws an exception, but merely returns {{false}}. That means that its return value shall be checked  and if it is {{false}} and a file still exists an exception should be thrown.
