TestProportionalCapacityPreemptionPolicy is failed for FairScheduler.
The following is error message:

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.
