> If there 10 workers running and if containers get killed , after a while we
> see that there are just 9 workers runnning. This is due to CONTAINER
> COMPLETED Event is not processed on AM side.
> Issue is in below code:
> {code:java}
> public void onContainersCompleted(List<ContainerStatus> statuses) {
> for (ContainerStatus status : statuses) {
> ContainerId containerId = status.getContainerId();
> ComponentInstance instance =
> liveInstances.get(status.getContainerId());
> if (instance == null) {
> LOG.warn(
> "Container {} Completed. No component instance exists.
> exitStatus={}. diagnostics={} ",
> containerId, status.getExitStatus(), status.getDiagnostics());
> return;
> }
> ComponentEvent event =
> new ComponentEvent(instance.getCompName(), CONTAINER_COMPLETED)
> .setStatus(status).setInstance(instance)
> .setContainerId(containerId);
> dispatcher.getEventHandler().handle(event);
> }
> {code}
> If component instance doesnt exist for a container, it doesnt iterate over
> other containers as its returning from method
