Jungtaek Lim commented on STORM-1730:
-------------------------------------

This is merged to master and 1.x-branch, but not 1.0.x-branch.

We should port back to 1.0.x-branch but I'm not sure what lowest version this will be included since we're in progress of release vote 1.0.2 RC3. So 1.0.2 or 1.0.3.

> When using the LocalCluster in test setup.  LocalCluster#shutdown() does not shutdown all executor services it starts.  In my test case, there is a single thread pool executor service that is not shutdown and not daemon.  This keeps the jvm alive when it is expected to terminate.
> Please see attached test case.  In my example, thread pool 47 is not shutdown.  Naming here is conditional on threading.
