> YARN has a --mount-cgroup operation in the
> [container-executor|https://github.com/apache/hadoop/blob/9c7b8cf54ea88833d54fc71a9612c448dc0eb78d/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/native/container-executor/impl/container-executor.c#L2929]
> which mounts each controller's cgroup folder to a specified path. In cgroup
> v2 the controller structure changed, it's flat now, so there are no more
> separate controller paths. To keep being compatible with v1 a new mount
> method should be added, but its functionality could be simplified quite a bit
> for v2.
