Andras Bokor commented on YARN-4994:

Hi [~jzhuge],

In the last two days I tried many different combinations to find out why the tests are failing.
In YARN-5034 you can see my last patch (patch 12). I changed only stop method to close and
the tests failed.
It does not make sense for me at all. Close() calls stop. How can it ruin the test results?
It seems not-intermittent. Always the same tests are failing I can reproduce builds with no
Do you have idea? It is very strange.
