> When a task is taking too long to localize and is killed by the AM due to
> task timeout, the job UI/history is not very helpful. The attempt simply
> lists a diagnostic stating it was killed due to timeout, but there are no
> logs for the attempt since it never actually got started. There are log
> messages on the NM that show the container never made it past localization by
> the time it was killed, but users often do not have access to those logs.
