             Summary: TestProportionalCapacityPreemptionPolicy is failed for FairScheduler
                 Key: YARN-2453
                 URL: https://issues.apache.org/jira/browse/YARN-2453
             Project: Hadoop YARN
          Issue Type: Bug

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

java.lang.AssertionError: Failed to find SchedulingMonitor service, please check what happened

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.
