----------------------------------------
[~sandflee] - more details on your experience would help. Any metrics on how
often the NM has to intervene? And, how long does it take for the NM to unblock
containers once everything is paused?
> Set OOM control for memory cgroups

> Key: YARN-4599
> URL: https://issues.apache.org/jira/browse/YARN-4599
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.9.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Attachments: yarn-4599-not-so-useful.patch
>
>
> YARN-1856 adds memory cgroups enforcing support. We should also explicitly
> set OOM control so that containers are not killed as soon as they go over
> their usage. Today, one could set the swappiness to control this, but
> clusters with swap turned off exist.
