Ahmed Hussein commented on MAPREDUCE-7079:
------------------------------------------
This test case has been failing for ever.
* When it timeout, {{MRAppMaster}} and some {{YarnChild}} processes remain
running in the background. Therefore, the JVM running the tests fail due to
OOM. No one notices that this unit test case has failed because the QA reports
the unit tests that failed, but not timeout.
* It works for Mac OS X, but never works for Linux running on a virtual Box. It
only works on the latter by disabling
{{MRJobConfig.MR_ENCRYPTED_INTERMEDIATE_DATA}}.
Going back to the commit that added the JUnit test, the test fails as well.
So, in order to avoid the bogus QA reports caused by this JUnit, I am going to
disable it until I figure out whether linux crashes because of entropy issues
on Virtual Machines.
