Jason Lowe commented on YARN-324:
---------------------------------
The nodemanager currently supports this via the
yarn.nodemanager.delete.debug-delay-sec property. Is that sufficient to meet
your needs or were you thinking of something different?
> Provide way to preserve container directories
> ---------------------------------------------
>
> Key: YARN-324
> URL: https://issues.apache.org/jira/browse/YARN-324
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager, resourcemanager
> Affects Versions: 2.0.3-alpha
> Reporter: Lohit Vijayarenu
>
> There should be a way to preserve container directories (along with
> filecache/appcache) for offline debugging. As of today, if container
> completes (either success or failure) it would get cleaned up. In case of
> failure it becomes very hard to debug to find out what the case of failure
> is. Having ability to preserve container directories will enable one to log
> into the machine and debug further for failures.
