Wangda Tan updated YARN-8372:
-----------------------------
Summary: Distributed shell app master should not release containers when
shutdown if keep-container is true (was: ApplicationAttemptNotFoundException
should be handled correctly by Distributed Shell App Master)
> Distributed shell app master should not release containers when shutdown if

> try {
> response = client.allocate(progress);
> } catch (ApplicationAttemptNotFoundException e) {
> handler.onShutdownRequest();
> LOG.info("Shutdown requested. Stopping callback.");
> return;{noformat}
> is a code snippet from AMRMClientAsyncImpl. The corresponding
> onShutdownRequest call for the Distributed Shell App master,
> {noformat}
> @Override
> public void onShutdownRequest() {
> done = true;
> }{noformat}
> Due to the above change, the current behavior is that whenever an application
> attempt fails due to a NM restart (NM where the DS AM is running), an
> ApplicationAttemptNotFoundException is thrown and all containers for that
> attempt including the ones that are running on other NMs are killed by the AM
> and marked as COMPLETE. The subsequent attempt spawns new containers just
> like a new attempt. This behavior is different to a Map Reduce application
> where the containers are not killed.
