Key: IOTDB-5886
URL: https://issues.apache.org/jira/browse/IOTDB-5886
Project: Apache IoTDB
Issue Type: Bug
Components: mpp-cluster
Affects Versions: master branch
Reporter: xiaozhihong
Assignee: Yongzao Dan
Attachments: image-2023-05-16-16-34-56-835.png, iotdb-common.properties, iotdb-confignode.properties, iotdb-datanode.properties
Branch : master
commit dd86d1aca25640d00063836883b4129b966ce7ca
Referring to the configuration file, on 3 servers, start 3C3D.
Use Benchmark to write data to them, when one of the nodes is readONLY, stop writing, when entering CLI query, show data region, readONLY node shows as leader now.
