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.
