Sunil G created YARN-1980:
-----------------------------

             Summary: Possible NPE in KillAMPreemptionPolicy related to ProportionalCapacityPreemptionPolicy
                 Key: YARN-1980
                 URL: https://issues.apache.org/jira/browse/YARN-1980
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.3.0
            Reporter: Sunil G


I configured KillAMPreemptionPolicy for My Application Master and tried to check preemption of queues.
In one scenario I have seen below NPE in my AM

014-04-24 15:11:08,860 ERROR [RMCommunicator Allocator] org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator: ERROR IN CONTACTING RM. 
java.lang.NullPointerException

	at java.lang.Thread.run(Thread.java:662)

I was using 2.2.0 and merged MAPREDUCE-5189 to see how AM preemption works.
