Arun Suresh commented on YARN-8808:
-----------------------------------
Also, it looks like you need to null check getNodeUtilization() /
getAggregatedContainersUtilization() - there seems to be case where you can get
an NPE if you don't
> Use aggregate container utilization instead of node utilization to determine
> resources available for oversubscription

> can be allocated to containers, hence the allocation threshold should be with
> respect to aggregate container utilization.
