                 URL: https://issues.apache.org/jira/browse/IOTDB-5931
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Cluster, mpp-cluster
            Reporter: 刘珍

测试版本：iotdb master 0524_12d67e0
问题1 ：
3副本3C21D集群，长时间循环运行 load tsfile ; delete 所有数据；show cluster 21D显式状态为Unkown，但是客户端仍然可以继续读写正常。
