hbaseregionserver节点下线

hbase 版本&＃xff1a;1.2.0-cdh5.7.0

进入到hmaster节点 hbase/bin目录

执行 

./graceful_stop.sh regionserver的主机名
此命令会先关闭Load Balancer&＃xff0c;然后Assigned Region&＃xff0c;之后会将regionserver节点关闭。

命令执行完毕后

在hbase web界面查看对应的regionserver节点为是dead的状态

重启hbase 集群&＃xff0c;可以在web界面不显示dead节点。

最后进入&＃xff1a;hbase shell 客户端

手动打开 load balancer
