Miklos Szegedi commented on YARN-4599:
--------------------------------------
Thank you for the patch [~sandflee]. This would be useful for many users.
I have a few questions.
1. CGroupsElasticMemoryResourceHandlerImpl copies lots of code from
CGroupsMemoryResourceHandlerImpl. Have you considered inheritance to reduce
redundancy?
2. Is it better to use JNI as in the current patch, or implement the event
logic in Linux Container Executor?
3. Could you please rebase it? It does not build anymore.

> 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.
