hive beeline使用

Posted 2022-12-06 海绵不老

1.hadoop集群启用 start-all.sh
2.注意开启hiveserver2
3.重新开启一个连接，输入beeline命令：
再输入： !connect jdbc:hive2://hadoop1:10000/default
紧接着输入用户名、密码

	[atguigu@hadoop1 root]$ beeline 
	Beeline version 1.2.1 by Apache Hive
	beeline> !connect jdbc:hive2://hadoop1:10000/default
	Connecting to jdbc:hive2://hadoop1:10000/default
	Enter username for jdbc:hive2://hadoop1:10000/default: atguigu
	Enter password for jdbc:hive2://hadoop1:10000/default: ******
	Connected to: Apache Hive (version 1.2.1)
	Driver: Hive JDBC (version 1.2.1)
	Transaction isolation: TRANSACTION_REPEATABLE_READ
	0: jdbc:hive2://hadoop1:10000/default> [atguigu@hadoop1 root]$ 

4.第二种方式：

   [atguigu@hadoop1 root]$ beeline -u "jdbc:hive2://localhost:10000"  -n atguigu -p  123456       
	Connecting to jdbc:hive2://localhost:10000
	Connected to: Apache Hive (version 1.2.1)
	Driver: Hive JDBC (version 1.2.1)
	Transaction isolation: TRANSACTION_REPEATABLE_READ
	Beeline version 1.2.1 by Apache Hive
	0: jdbc:hive2://localhost:10000> select * from emp;
