>
> Currently, for any exceptions thrown on the allocate call of AMRMClientAsync,
> it will stop both heartbeat thread and the callback handler thread, leaving
> AMRMClient in an unusable state. Caller has to instantiate a new AMRMClient.
> IMO, the threads should keep on running, it should be up to the caller
> whether to stop the AMRMClient or not.
> {code}
> try {
> response = client.allocate(progress);
> } catch (ApplicationAttemptNotFoundException e) {
> handler.onShutdownRequest();
> LOG.info("Shutdown requested. Stopping callback.");
> return;
> } catch (Throwable ex) {
> LOG.error("Exception on heartbeat", ex);
> savedException = ex;
> // interrupt handler thread in case it waiting on the queue
> handlerThread.interrupt();
> return;
> }
> {code}
