Miklos Szegedi commented on YARN-7693:
--------------------------------------

[~yangjiandan], thank you for raising this. How is jira this related to YARN-7064? I believe
a new resource calculator is enough in order to use cgroups for oversubscription resource
measurement.

> Currently ContainersMonitor has only one default implementation ContainersMonitorImpl,
> After introducing Opportunistic Container, ContainersMonitor needs to monitor system
metrics and even dynamically adjust Opportunistic and Guaranteed resources in the cgroup,
so another ContainersMonitor may need to be implemented. 
> The current ContainerManagerImpl ContainersMonitorImpl direct new ContainerManagerImpl,
so ContainersMonitor need to be configurable.
