Key: RATIS-1298
URL: https://issues.apache.org/jira/browse/RATIS-1298
Project: Ratis
Issue Type: New Feature
Reporter: Rui Wang
Assignee: Rui Wang
It's time to add the non-voting member, or leaner that is proposed in Raft
thesis 4.2.1 (you can find a copy at [1]).
The leaner is useful to maintain high availability when new servers join Raft
ring (details at thesis 4.2.1). For Ozone SCM HA effort, we have also discussed
the possibility to utilize leaner as the tool to replace SCM nodes online.
