Carlo Curino commented on YARN-3481:
------------------------------------

I agree with [~vinodkv]... let's go for the new ResourceUtilization record, it 
allows you to evolve independently of whatever policing it is done for 
Resource. Try to keep the code structure/style very consistent, as the two are 
closely related.

> Report NM aggregated container resource utilization in heartbeat

>                 Key: YARN-3481
>                 URL: https://issues.apache.org/jira/browse/YARN-3481
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: nodemanager, resourcemanager
>    Affects Versions: 2.7.0
>            Reporter: Inigo Goiri
>   Original Estimate: 336h
>  Remaining Estimate: 336h
>
> To allow the RM take better scheduling decisions, it should be aware of the 
> actual utilization of the containers. The NM would aggregate the 
> ContainerMetrics and report it in every heartbeat.
> Related to YARN-1012 but aggregated to reduce the heartbeat overhead.
