Jason Lowe commented on YARN-4839:
----------------------------------
This appears to have been fixed as a side-effect of YARN-3361 which wasn't in
the build that reproduced this issue. That change updated getMasterContainer
to avoid locking the RMAppAttemptImpl.
> ResourceManager deadlock between RMAppAttemptImpl and
> SchedulerApplicationAttempt

> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.8.0
> Reporter: Jason Lowe
> Priority: Blocker
>
> Hit a deadlock in the ResourceManager as one thread was holding the
