> Key: YARN-9815
> URL: https://issues.apache.org/jira/browse/YARN-9815
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Reporter: Ahmed Hussein
> Assignee: Ahmed Hussein
> Priority: Minor
> Attachments: YARN-9805.001.patch, YARN-9815.001.patch,
> YARN-9815.002.patch
>
>
> Running ReservationACLsTestBase throws a NPE running the FairScheduler. Old
> revisions back in 2016 also throw NPE.
> In the test case, QueueC does not have reserveACLs, so
> ReservationsACLsManager would throw NPE when it tries to access the ACL on
> line 82.
> I still could not find what was the first revision that caused this test case
> to fail. I stopped at bbfaf3c2712c9ba82b0f8423bdeb314bf505a692 which was
> working fine.
> I have OsX with java 1.8.0_201
>
> {code:java}
