Inigo Goiri commented on YARN-3481:
-----------------------------------
It requires the implementation of ResourceUtilization.
> 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.
