Bibin Chundatt commented on YARN-10475:
---------------------------------------
Thank you [~Jim_Brennan] working on this.
Could you make the implementation generics to plugin other policies too. Cpu
utlization only of the policy which helps in deciding the HB interval. thoughts?
> Scale RM-NM heartbeat interval based on node utilization

> Key: YARN-10475
> URL: https://issues.apache.org/jira/browse/YARN-10475
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 2.10.1, 3.4.1
> Reporter: Jim Brennan
> Assignee: Jim Brennan
> Priority: Minor
> Attachments: YARN-10475.001.patch, YARN-10475.002.patch,
> YARN-10475.003.patch
>
>
> Add the ability to scale the RM-NM heartbeat interval based on node cpu
> utilization compared to overall cluster cpu utilization. If a node is
> over-utilized compared to the rest of the cluster, it's heartbeat interval
> slows down. If it is under-utilized compared to the rest of the cluster,
> it's heartbeat interval speeds up.
> This is a feature we have been running with internally in production for
> several years. It was developed by [~nroberts], based on the observation
> that larger faster nodes on our cluster were under-utilized compared to
> smaller slower nodes.
> This feature is dependent on [YARN-10450], which added cluster-wide
> utilization metrics.
