> error would occurs when starting datanode 2 times and all nodes seems normal
> with show cluster
> reproduction:
> # start a 3C3D iotdb cluster successfully
> # run start-datanode.sh on 1 node without stopping it
>
> actual result:
> # show cluster shows all confignode and datanode is running
> # but error occurs when create timeseries !image-2022-10-27-11-15-54-884.png!
>
> 建议：
> # 在start-confignode.sh 和 start-datanode.sh 脚本中，应该先判断是否已经有启动的服务，如果有，先停止，然后再启动。
> # 咱们的stop-datanode.sh
> 内停止服务的方式不对，现状是使用ps然后查找datanode字样。一般通用做法是，在启动时将PID记录在pid文件中，停止时，读取并kill。目前的做法容易误停止其他服务（或者有多个时直接报错）。
