Closing: 0: jdbc:hive2://linux02:10000

关停 HiveServer2 服务

查看 HiveServer2 进程
ps -ef | grep HiveServer2 | grep -v grep
输出类似：
root      87274  87180  2 22:13 pts/1    00:01:36 /opt/apps/jdk1.8/bin/java ... 
杀死进程
kill -9 87274
验证是否已关停
# 再查进程
ps -ef | grep HiveServer2 | grep -v grep

# 或查端口 10000
netstat -tulnp | grep 10000

hadoop 关停
