Naganarasimha G R updated YARN-3562:
------------------------------------
    Description: 
*Issues reported from MAPREDUCE-6337* :
A bunch of MR unit tests are failing on our branch whenever the mini YARN 
cluster needs to bring up multiple node managers.

For example, see 
https://builds.apache.org/job/PreCommit-MAPREDUCE-Build/5472/testReport/org.apache.hadoop.mapred/TestClusterMapReduceTestCase/testMapReduceRestarting/

It is because the NMCollectorService is using a fixed port for the RPC (8048).

*Issues reported from YARN-3044* :
Test case failures and tools(FB & CS) issues found :
# find bugs issue : Comparison of String objects using == or != in 
ResourceTrackerService.updateAppCollectorsMap
# find bugs issue : Boxing/unboxing to parse a primitive 
RMTimelineCollectorManager.postPut. Called method Long.longValue()
Should call Long.parseLong(String) instead.
# hadoop.yarn.server.resourcemanager.TestAppManager, 
hadoop.yarn.server.resourcemanager.rmapp.TestRMAppTransitions, 
hadoop.yarn.server.resourcemanager.TestClientRMService & 
hadoop.yarn.server.resourcemanager.logaggregationstatus.TestRMAppLogAggregationStatus,
