hive基础知识

#后台启动
>bin/hiveserver2 &
#进入beeline
>bin/beeline
#连接ip是部署hive的服务器，端口默认 10000；可在conf/hive-site.xml修改hive.server2.thrift.port属性值 
!connect jdbc:hive2://ip:端口
>输入用户名 默认空
>输入密码 默认空
#连接成功后，即可看到Beeline version 2.3.4 by Apache Hive当前版本。于引入的jar相对应
#查看数据库
>show databases;
#使用default库
>use default;
#即可进行显示表，查询等
>show tables;
>select * from 表名 limit 1,10;
