> *What's the problem ?*
> There are 3 datanodes in a group: leader, follower1, follower2, then I find
> the leader and follower1 both remove a group, but follower2 does not remove
> the group. Then follower2 begin infinite LeaderElection, but the leader and
> follower1 response group not found.

> and follower1 remove group-41A4E88EB002 at 2020-04-18 01:17:17. But follower2
> try to elect leader of group-41A4E88EB002 until 2020-04-18 07:56:42, at when
> I capture the following screenshot.
