> TestMiniMRWithDFS fails sporadically with the following error:
> junit.framework.AssertionFailedError: Spurious directory task_0001_m_000008_0 found in C:\hudson\workspace\Hadoop-WindowsSmokeTest\trunk\build\test\mapred\local\50068_0
> 	at org.apache.hadoop.mapred.TestMiniMRWithDFS.checkTaskDirectories(TestMiniMRWithDFS.java:128)
> 	at org.apache.hadoop.mapred.TestMiniMRWithDFS.testWithDFS(TestMiniMRWithDFS.java:163)
> This tests checks that all mapred.local.dirs have been cleaned up after running a mapred job on MiniMRCluster.  Effectively, this tests waits for TaskTracker.isIdle() to return true before checking the dirs have been cleaned up.  I believe that HADOOP-639 reordered the cleanup code so that isIdle() will return true before the directory cleanup is complete.
