> 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.
