The test TestMiniMRWithDFS.checkTaskDirectories is checking for task directories incorrectly
--------------------------------------------------------------------------------------------

                 Key: HADOOP-4409
                 URL: https://issues.apache.org/jira/browse/HADOOP-4409
             Project: Hadoop Core
          Issue Type: Test
          Components: mapred, test
            Reporter: Hemanth Yamijala


The check for task directories in {{TestMiniMRWithDFS.checkTaskDirectories}} seems incorrect.
The following code:
{code}
assertTrue("task tracker dir " + trackerDir + " does not exist.", 
                 trackerDir.isDirectory());
{code}
in the test case seems to assume that every configured task tracker has the task tracker directory
{{TaskTracker.SUBDIR}} created. However, this directory is only created if any task is assigned
to the task tracker. As there is no real control over which task trackers will actually be
assigned tasks, it seems an incorrect check.
