----------------------------------

             Summary: Reinforce Cluster IT framework's startup check
                 Key: IOTDB-3825
                 URL: https://issues.apache.org/jira/browse/IOTDB-3825
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Yongzao Dan
            Assignee: 伊丹翔
             Fix For: 0.14.0


Currently, the cluster IT framework determines the successful startup of a cluster based on the client's ability to connect to any DataNode in the cluster.

 

However, from the  ConfigNode's perspective, a DataNode is successfully started if and only if it can receive the ConfigNode's heartbeat.

 

Therefore, the cluster built by the Cluster IT framework is successfully started only when the _show cluster_ request returns all nodes in the RUNNING state.
