tidb4.0剔除节点

环境：tidb4.0、centos7
1、查看集群节点信息
1	`tiup cluster display tidb`
2、剔除节点
tiup cluster scale-in tidb --node 172.21.210.39:20160
其中 --node 参数为需要下线节点的 ID。
预期输出 Scaled cluster <cluster-name> in successfully 信息，表示缩容操作成功。
 
[root@host-172-21-210-32 ~]# tiup cluster scale-in tidb --node 172.21.210.39:20160
Starting component `cluster`:  scale-in tidb --node 172.21.210.39:20160
This operation will delete the 172.21.210.39:20160 nodes in `tidb` and all their data.
Do you want to continue? [y/N]: y
Scale-in nodes...
