I went through the approach, but was wondering its not covering the scenario
with resource profiles, if multiple resource types are supported then this
would be like not a proper solution in terms of the Object
{{ResourceUtilization}} being returned & changes in {{ContainerStatusPBImpl}}
by storing only cpu, vmem and pmem as concatenated string.
Was wondering whether we need to return {{ResourceInformation}} and store
resource type information and individual resource values as separate key value
pairs in the {{ContainerStatusPBImpl.containerAttributes}} map ?

> 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.
