John Zhuge commented on YARN-4994:
----------------------------------

+1 LGTM

javac warnings:
* YARN-5007 to fix the deprecated warnings

checkstyle warnings:
* Ignore the warning about 
{{TestJobHistoryEventHandler#testTimelineEventHandling}} being longer than 150 
lines. Leave it to the next poor soul. If you are really in the mood, you can 
get it down to 150 by replacing {{tEntity.getEvents()}} with a var {{events}}.

Unit test failures:
* TestAMRMProxy: same failures on a clean stock build, so ignore.
* Other failures: unrelated to the changes.

> Use MiniYARNCluster with try-with-resources in tests

> In tests MiniYARNCluster is used with the following pattern:
> In try-catch block create a MiniYARNCluster instance and in finally block 
> close it.
> [Try-with-resources|https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html]
>  is preferred since Java7 instead of the pattern above.
