Gaofei Cao commented on IOTDB-4354:
-----------------------------------
The cluster/ratis are work normally only when more than half replicas are work.
In this situation, ratis has 3 replicas(but down 2 replicas), it cannot change
leader.
> 【0】[ confignode ] The leader of the schemaregion is displayed on the node
> that has been down
