[jira] [Created] (RATIS-97) Leader may not have majority after
setConfiguration
Tsz Wo Nicholas Sze created RATIS-97:
----------------------------------------
Summary: Leader may not have majority after setConfiguration
Key: RATIS-97
URL: https://issues.apache.org/jira/browse/RATIS-97
Project: Ratis
Issue Type: Bug
Reporter: Tsz Wo Nicholas Sze
Assignee: Tsz Wo Nicholas Sze
Here is an example: Suppose a group has 3 servers and one of them is the leader. Use setConfiguration to add 6 more servers. The leader is still running as a leader although it does not has majority anymore. The 6 new servers may elect a new leader among them. Finally, there are two leaders in the group.
