> The IPC thread logs some other activity 250ms later, so it's not stuck nor did it log an error.

> The attempt was not running in LLAP.
> However, the attempt does come up again when the DAG is killed, long time after it was stuck; presumably, AM failed to detect the failure (or heartbeat failure for that matter?) and never tried to reschedule.

> It seems like a parallel query caused the memory exhaustion on LLAP; most mappers for this job eventually completed successfully, a few were lost as per above, and the DAG got stuck because of that.
