前提先要启动hiveserver2,不启动怎么连接呢.

 hive --service hiveserver2 &

方式1

先登录beeline,进入beeline的命令行环境,然后连接

[root@mypc01 conf]# beeline
beeline> !connect jdbc:hive2://192.168.xx.101:10000
Connecting to jdbc:hive2://192.168.xx.101:10000

方式二

一步到位

beeline -u jdbc:hive2://192.168.xx.101:10000 -n root

总结

• 首先要启动hiveserver2
• 用beeline连接hive有两种方式,第二种简单些
