Subject [jira] [Commented] (YARN-5385) Add a PriorityAgent in ReservationSystem
Date Tue, 28 Feb 2017 01:48:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-5385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15887042#comment-15887042
] 

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.
