Zhijie Shen created YARN-489:
--------------------------------

             Summary: Setter of xxxxPBImpl doesn't really set the collection, 
but append its items to an existing collection
                 Key: YARN-489
                 URL: https://issues.apache.org/jira/browse/YARN-489
             Project: Hadoop YARN
          Issue Type: Bug
         Environment: For example, AMResponsePBImpl#setAllocatedContainers, 
AMResponsePBImpl#setUpdatedNodes and CountersPBImpl#addAllCounterGroups.

What if the collection from proto or builder is not empty? We need to 
investigate the issue to ensure all cases of collection setter are handled 
correctly.
