> HadoopTimelineMetricsSink has and ExecutorService thread which is not a
> daemon thread. The executor is not shutdown, and thread is not interrupted
> while the sink stops. This causes region server process to hang although the
> rest of the threads have all exited.
> The new thread should be marked as a daemon thread, and also call shutdown()
> or shutdownNow() on the executor in sink close.
