Key: IOTDB-4361
URL: https://issues.apache.org/jira/browse/IOTDB-4361
Project: Apache IoTDB
Issue Type: Improvement
Reporter: 伊丹翔
Assignee: 伊丹翔
we should add a precheck when the confignode executes removing datanode :
# Make sure the node which execute addRegionPeer is in running
# Throw an error which says it's not supported to remove the datanode because
the configuration of the cluster is only one replication.
