> Application is hung without timeout and retry after DNS/network is down.
> It is because right after the container is allocated for the AM, the
> DNS/network is down for the node which has the AM container.
> The application attempt is at state RMAppAttemptState.SCHEDULED, it receive
> RMAppAttemptEventType.CONTAINER_ALLOCATED event, because the
> IllegalArgumentException(due to DNS error) happened, it stay at state
> RMAppAttemptState.SCHEDULED. In the state machine, only two events will be
> processed at this state:
> RMAppAttemptEventType.CONTAINER_ALLOCATED and RMAppAttemptEventType.KILL.
> The code didn't handle the event(RMAppAttemptEventType.CONTAINER_FINISHED)
> which will be generated when the node and container timeout. So even the node
> is removed, the Application is still hung in this state
> RMAppAttemptState.SCHEDULED.
> The only way to make the application exit this state is to send
> RMAppAttemptEventType.KILL event which will only be generated when you
> manually kill the application from Job Client by forceKillApplication.
> To fix the issue, we should add an entry in the state machine table to handle
> RMAppAttemptEventType.CONTAINER_FINISHED event at state
> RMAppAttemptState.SCHEDULED
> add the following code in StateMachineFactory:
> {code}.addTransition(RMAppAttemptState.SCHEDULED,
> RMAppAttemptState.FINAL_SAVING,
> RMAppAttemptEventType.CONTAINER_FINISHED,
> new FinalSavingTransition(
> new AMContainerCrashedBeforeRunningTransition(),
> RMAppAttemptState.FAILED)){code}
