      Description

      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

      This test should only work for capacity scheduler because the following source code in ResourceManager.java prove it will only work for capacity scheduler.

      if (scheduler instanceof PreemptableResourceScheduler
                && conf.getBoolean(YarnConfiguration.RM_SCHEDULER_ENABLE_MONITORS,
                YarnConfiguration.DEFAULT_RM_SCHEDULER_ENABLE_MONITORS)) {
      

      Because CapacityScheduler is instance of PreemptableResourceScheduler and FairScheduler is not instance of PreemptableResourceScheduler.
      I will upload a patch to fix this issue.
