[~haibochen], thank you for the patch.

The else branch should return {{Optional.of(false);}}

> YARN-4599 adds elastic memory control that disables oom killer for the root
> container cgroup. Hence, all containers have their oom killer disabled
> because they inherit the setting from the root container cgroup. Hence, when
> strict memory control on individual containers is also enabled, the container
> will be frozen but not killed. We can let the container monitoring thread to
> take care of the frozen containers.
