Tsz-wo Sze commented on RATIS-967:
----------------------------------
No sure why they need two priority values. It seems a single value is good
enough. Every server has a priority and every server can start an election.
When a lower priority server ask a higher priority server to vote, the lower
priority server will abort the election if the higher priority server replies.
If the leader can heartbeat to a higher priority server, it will step down
automatically.
> Transfer leadership from leader to follower
