> 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.
