You want to write the shell command or the script to release_agent in the
cgroup ? The Shell command or the script that can delete the hierarchy or the
container empty dirs.

Yes. The demo could be found at

Please feel free to work on it. Sorry for it. I was busy at that time and
forgot it...:(

> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.5.2
> Reporter: lachisis
> Assignee: Jun Gong
>
> If we use LinuxContainerExecutor to executor the containers, this question
> may happens.
> In the common case, when a container run, a corresponding hierarchy will be
> created in cgroup dir. And when the container terminate, the hierarchy will
> be delete in some seconds(this time can be configured by
> yarn.nodemanager.linux-container-executor.cgroups.delete-delay-ms).
> In the code, I find that, CgroupsLCEResource send a signal to kill container
> process asynchronously, and in the same time, it will try to delete the
> container hierarchy in configured "delete-delay-ms" times.
> But if the container process be killed for seconds which large than
> "delete-delay-ms" time, the container hierarchy will remain for ever.
