    Description

      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.
