ASF GitHub Bot updated YARN-11965:
----------------------------------
Labels: pull-request-available (was: )
> Support partition-aware resource metrics in RM cluster metrics REST API
> -----------------------------------------------------------------------
>
> Key: YARN-11965
> URL: https://issues.apache.org/jira/browse/YARN-11965
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Chenyu Zheng
> Assignee: Chenyu Zheng
> Priority: Major
> Labels: pull-request-available
>
> When node labels are enabled, different labels represent separate resource
> pools. However, the RM REST API `/ws/v1/cluster/metrics` currently exposes
> fields such as totalMB and totalVirtualCores based on the default partition
> only. As a result, resources from non-default partitions are not visible to
> external resource management systems, which may incorrectly determine that
> the cluster has no available capacity after new labels are added.
> The API should expose cluster resource metrics across all partitions and
> provide partition-level metrics so clients can distinguish capacity and usage
> by node label.
