> Similar with https://issues.apache.org/jira/browse/MAPREDUCE-7475 , 5 more 
> non-idempotent unit tests are detected.
> The following two tests below do not reset `NotificationServlet.counter`, so 
> repeated runs throw assertion failures due to accumulation:
>  * org.apache.hadoop.mapred.TestClusterMRNotification#testMR
>  * org.apache.hadoop.mapred.TestLocalMRNotification#testMR
> The following test does not remove the key `AMParams.ATTEMPT_STATE`, so 
> repeated runs of the test will not be missing the attempt-state at all:
>  * org.apache.hadoop.mapreduce.v2.app.webapp.TestAppController.testAttempts
> The following test fully deletes `TEST_ROOT_DIR` after execution, so repeated 
> runs will throw a`DiskErrorException`:
>  * org.apache.hadoop.mapred.TestMapTask#testShufflePermissions
> The following test does not restore the static variable `statusUpdateTimes` 
> after execution, so consecutive runs throws `AssertionError`:
>  * org.apache.hadoop.mapred.TestTaskProgressReporter#testTaskProgress
