Andras Bokor commented on YARN-4994:
------------------------------------
It seems the test failures are not related.
I thought Hadoop QA runs all the tests on every patch. Actually, it does not,
so when I added just some files the tests in org.apache.hadoop.yarn package did
not run. That is why I did not see tests failure in some cases and I saw when I
added particular changes.
You can check YARN-5034:YARN-5034.13.patch. I changed only a comment and the
same tests failed. Can I consider as the test failures are not related?
If so, I will do the suggested changes and update the new patch tomorrow.

> In try-catch block create a MiniYARNCluster instance and in finally block
> close it.
