    Attachment: YARN-5092.002.patch

Thanks for the review, Rohith!

Good catch on the rm1.stop() suggestion.  Clearing the queue metrics wasn't causing the default metrics exception, that was the failure to stop. Clearing the queue metrics fixed the class cast exception, but I went ahead with your suggestion to remove the scheduler setting as another way to fix it since it seemed unrelated to the test.

Also added the setLoginUser change in the setup method.  Tested both orderings of the tests.
