Sean Po commented on YARN-5385:
-------------------------------

Two of the test failures are accounted for with a JIRA.

YARN-6231 - 
hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairScheduler::testMoveWouldViolateMaxResourcesConstraints
YARN-5548 - 
org.apache.hadoop.yarn.server.resourcemanager.TestRMRestart::testFinishedAppRemovalAfterRMRestart

The remaining failure 
hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairSchedulerPreemption::testPreemptionSelectNonAMContainer
 appears to be a flaky test. A local run of the test was very inconsistent, 
with some fails and some successes across multiple tests. YARN-6249 was created 
to track this problem.
