> URL: https://issues.apache.org/jira/browse/RATIS-1001
> Project: Ratis
> Issue Type: Improvement
> Components: server
> Reporter: Glen Geng
> Assignee: Glen Geng
> Priority: Major
>
>
> During SCM-HA, SCM not only needs to know whether it is a leader, but also
> needs to know which term it is in charge of.
>
> Assume such a case: underlying raft node was leader on term 1, then step down
> as follower on term 2, then init election and become leader again on term 3.
> If term is not exposed together with leader information, SCM can not
> distinguish a leader of term 1 from that of term 3.
