Description

UI2 makes a REST call to TimelineReader without cluster name. It is advised to make a REST call with clusters/

{cluster name}

so that remote TimelineReader daemon could serve for different clusters.
Example:
Current: /ws/v2/timeline/flows/
Change: /ws/v2/timeline/clusters/{cluster name}/flows/

*yarn.resourcemanager.cluster-id *is configured with cluster. So, this config could be used to get cluster-id
