刘珍 created IOTDB-5611:
-------------------------

             Summary: Supports removing zombie nodes
                 Key: IOTDB-5611
                 URL: https://issues.apache.org/jira/browse/IOTDB-5611
             Project: Apache IoTDB
          Issue Type: Wish
          Components: mpp-cluster
            Reporter: 刘珍
            Assignee: Xinyu Tan

应用中,因为误操作或其他故障,导致某些节点,无法恢复到正常状态,希望集群支持(强制)移除故障节点。

测试流程:
1. 误操作(脚本忘记修改ConfigNode IP),把ip11/12/13 误加入 其他集群(集群1)
2.没有按正常流程缩容,而是停止ip11/12/13 datanode的服务,删除data目录
3.把ip11/12/13 从集群1 中移除,通过remove-datanode.sh方式移除,会报错,{color:red}*希望能有方式支持从集群中删除故障节点。*{color}
{color:red}*SQL方式:连接到集群1 ,执行SQL 移除故障节点,或其他方式。*{color}
步骤2执行后,集群1的状态

步骤3,通过remove-datanode.sh,在ip11本机执行(它已经下线,就算data还在,怎么与集群1通信)
