Brook Zhou commented on YARN-5451:
----------------------------------
Is this because the ContainerLocalizer is launched in a separate process from
LCE with a timeOutInterval of 0?
> Container localizers that hang are not cleaned up
> -------------------------------------------------

> Key: YARN-5451
> URL: https://issues.apache.org/jira/browse/YARN-5451
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.6.0
> Reporter: Jason Lowe
>
> I ran across an old, rogue process on one of our nodes. It apparently was a
> container localizer that somehow entered an infinite loop during startup.
> The NM never cleaned up this broken localizer, so it happily ran forever.
> The NM needs to do a better job of tracking localizers, including killing
> them if they appear to be hung/broken.
