----------------------------------
Move it out of 2.6.4 given no update on this JIRA for a while.
> Persist ClusterMetrics across RM HA transitions
> -----------------------------------------------
>
> Key: YARN-1848
> URL: https://issues.apache.org/jira/browse/YARN-1848
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Affects Versions: 2.4.0
> Reporter: Karthik Kambatla
>
> Post YARN-1705, ClusterMetrics are reset on transition to standby. This is
> acceptable as the metrics show statistics since an RM has become active.
> Users might want to see metrics since the cluster was ever started.
