    [ https://issues.apache.org/jira/browse/YARN-5865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15667503#comment-15667503

-----------------------------------------

some more comments on the patch
AppInfo.java
# After current patch change, you can remove app.getApplicationSubmissionContext(); 

RMAppManager.java
# line 401, 402, 403 has not changed. Looks like format has changed. Can you revert this ?
# line 571, can you check if (app.isAppInCompletedStates()) immediately after holding applicationId
lock? It is not an issue, just not to create future object. 
# line 580, can you flip code for checking priority equals and do futures.get like below?

{code}
	      if (app.getApplicationPriority().equals(appPriority)) {
	        return;
	      }
          Futures.get(future, YarnException.class);
{code}

RMApp.java
# Java doc for API isAppInCompletedStates is repeated i.e *completed/completed states*. It
should be completing/completed. 

YarnScheduler.java
# Return type of API has changed from void to Priority. I am not sure does it breaks. cc:/[~jianhe]
