unit tests which alter persistent state should call cleanup before running
--------------------------------------------------------------------------

                 Key: HDFS-2967
                 URL: https://issues.apache.org/jira/browse/HDFS-2967
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Colin Patrick McCabe
            Priority: Minor


I did a little test, and found that aborting unit tests halfway through (for example, with the stop button in Eclipse) will NOT invoke the @After functions.

Needless to say, this could have bad consequences for test users.  A developer might press control-C in the middle of a unit test, and then find that he was unable to successfully re-run that test again because of the lingering state.  A Jenkins build machine might experience a JVM crash because of an out-of-memory condition, and then find that all builds turned red because a unit test failed to clean up the state which it created.

I think that in HDFS tests which alter persistent state, we probably should invoke the @After functions from a @Before function, just to make sure that the necessary cleanup is done.
