> Key: YARN-5905
> URL: https://issues.apache.org/jira/browse/YARN-5905
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: federation, resourcemanager
> Affects Versions: YARN-2915
> Reporter: Subru Krishnan
> Assignee: Subru Krishnan
> Priority: Minor
> Attachments: YARN-5905-v1.patch
>
>
> Currently when RM HA is enabled, the webapp host is randomly picked from one
> of the ensemble RMs and relies on redirect to pick the active primary RM.
> This has a few shortcomings:
> * There's an overhead of additional network hop.
> * Sometimes the rmId selected might be an instance which is
> inactive/decommissioned
> * In few of our clusters, we have redirects disabled (either in client or
> server side) and then the invocation fails.
> This JIRA proposes updating the RM webapp host that is reported as part of
> Federation membership to the current primary RM's IP.
