--------------------------------

             Summary: Yarn Service Container Completed event doesn't get processed 
                 Key: YARN-10341
                 URL: https://issues.apache.org/jira/browse/YARN-10341
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bilwa S T
            Assignee: Bilwa S T


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
