Job directories could remain undeleted in some scenarios after job completes.
-----------------------------------------------------------------------------

                 Key: HADOOP-5248
                 URL: https://issues.apache.org/jira/browse/HADOOP-5248
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Hemanth Yamijala


I observed a couple of times that when a job has completed, its job directories were not cleaned
up. In discussion, it seems like there is a condition when only reduces from a job are run
on a machine and no maps, the TT does not get a signal from the JT to delete the files and
could be left behind. FYI, JVM reuse was enabled at the time. I can confirm that 'KillJobAction'
was not received by the TT.
