TestProportionalCapacityPreemptionPolicy is failed for FairScheduler. The following is error message: Running org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.TestProportionalCapacityPreemptionPolicy Tests run: 18, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.94 sec <<< FAILURE! - in org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.TestProportionalCapacityPreemptionPolicy testPolicyInitializeAfterSchedulerInitialized(org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.TestProportionalCapacityPreemptionPolicy) Time elapsed: 1.61 sec <<< FAILURE! java.lang.AssertionError: Failed to find SchedulingMonitor service, please check what happened at org.junit.Assert.fail(Assert.java:88) at org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.TestProportionalCapacityPreemptionPolicy.testPolicyInitializeAfterSchedulerInitialized(TestProportionalCapacityPreemptionPolicy.java:469) This test should only work for capacity scheduler because the following source code in ResourceManager.java prove it will only work for capacity scheduler. {code} if (scheduler instanceof PreemptableResourceScheduler && conf.getBoolean(YarnConfiguration.RM_SCHEDULER_ENABLE_MONITORS, YarnConfiguration.DEFAULT_RM_SCHEDULER_ENABLE_MONITORS)) { {code} Because CapacityScheduler is instance of PreemptableResourceScheduler and FairScheduler is not instance of PreemptableResourceScheduler. I will upload a patch to fix this issue. -- This message was sent by Atlassian JIRA (v6.2#6252)
