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.
> ContainersMonitor support configurable

> 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.
