Yang Wang updated YARN-6578:
----------------------------
Description:
When the applicationMaster wants to change(increase/decrease) resources of an
allocated container, resource utilization is an important reference indicator
for decision making. So, when AM call NMClient.getContainerStatus, resource
utilization needs to be returned.
Also container resource utilization need to report to RM to make better
scheduling.
So put resource utilization in ContainerStatus.
