> Run cgroup subsystems before moving the target PID.

> Key: MESOS-9805
> URL: https://issues.apache.org/jira/browse/MESOS-9805
> Project: Mesos
> Issue Type: Improvement
> Components: containerization
> Reporter: James Peach
> Priority: Major
>
> Currently, the Pid targeted by the cgroups isolator is moved into the cgroup
> before the subsystem runs to apply any type-specific cgroup configuration. We
> should reverse the order of this so that the PID is only moved once the
> cgroup is fully configured by the subsystem.
> The specific use case that affected us was where a PID was assigned to a
> {{net_cls}} cgroup before that cgroup had the class ID set. This caused a
> separate system to become confused.
