[jira] [Commented] (STORM-1730) LocalCluster#shutdown() does not terminate all storm threads/thread pools.

    STORM-1730 LocalCluster#shutdown() does not terminate all storm threads/thread pools.

    The thread pool executor used by the `DisruptorQueue.FlusherPool` is in a static context of the
    DisruptorQueue.  To avoid major changes to how this queues lifecycle is
    managed I added a simple fix is to create a thread pool factory which creates daemon
    threads.  The threads are now also named with the 'disruptor-flush'
    prefix to be consistent with the TimerTask.

    STORM-1730 LocalCluster#shutdown() does not terminate all storm
    threads/thread pools.
    
    The thread pool that is remaining is in a static context of the
    DisruptorQueue.  To avoid major changes to how this queues lifecycle is
    managed the fix is to create a thread pool factory which creates daemon
    threads.  The threads are now also named with the 'disruptor-flush'
    prefix to be consistent with the TimerTask.

> 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.
