------------------------------
Resolution: Duplicate
> SCM UI not showing correct HA roles
> -----------------------------------
>
> Key: HDDS-6728
> URL: https://issues.apache.org/jira/browse/HDDS-6728
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Janus Chow
> Assignee: Janus Chow
> Priority: Major
> Labels: pull-request-available

> The current logic to decide the LEADER of SCM is to check if the RaftPeer is
> local,
> [https://github.com/apache/ozone/blob/master/hadoop-hdds/server-scm/src/main/java/org/apache/hadoop/hdds/scm/ha/SCMRatisServerImpl.java#L268]
> I assuem this is because the "scm roles" requests are forwarded to the LEADER
> SCM, so the invoker is always the leader, thus "isLocal" is used to decide
> which SCM is LEADER.
> But in SCM UI, the "SCM HA (roles)" information are retrived by invoking
> "getRatisRoles" by each SCM, not forwarded to the LEADER SCM, thus each SCM
> will consider itself as the LEADER in UI.
> This ticket is to fix this issue.
