Actually, I have written a much better test case for this some time ago,
see
https://github.com/apache/flink/blob/142912b031df42d2abe43b41e98be5596cb3a7f9/flink-runtime/src/test/java/org/apache/flink/runtime/resourcemanager/ClusterShutdownITCase.java
So I would only merge the addition to the ResourceManager shutdown.
> Explicitly kill TaskManager on YARN when ApplicationMaster is shutting down

> Key: FLINK-4555
> URL: https://issues.apache.org/jira/browse/FLINK-4555
> Project: Flink
> Issue Type: Bug
> Components: YARN Client
> Affects Versions: 1.1.0
> Reporter: Robert Metzger
> Assignee: Maximilian Michels
> Priority: Critical
>
> It seems that Flink is not explicitly destroying the TaskManager JVM when the
> ApplicationMaster is shutting down (when the YARN application is stopping).
> Since this was once in Flink (in 1.0.x) we should add a test case to ensure
> this feature stays in the code.
