> When the ApplicationMaster shuts down it's supposed to remove the staging
> directory, assuming properties weren't set to override this behavior. During
> shutdown the AM tells the ResourceManager that it has finished before it
> cleans up the staging directory. However upon hearing the AM has finished,
> the RM turns right around and kills the AM container. If the AM is too slow,
> the AM will be killed before the staging directory is removed.
> We're seeing the AM lose this race fairly consistently on our clusters, and
> the lack of staging directory cleanup quickly leads to filesystem quota
> issues for some users.
