beeline 参数

Beeline工作模式有两种，即本地嵌入模式和远程模式。嵌入模式情况下，它返回一个嵌入式的Hive（类似于Hive CLI）。而远程模式则是通过Thrift协议与某个单独的HiveServer2进程进行连接通信。

下面给一个简单的登录Beeline的使用实例：

[html] view plain copy

% bin/beeline
Hive version 0.11.0-SNAPSHOT by Apache
beeline> !connect jdbc:hive2://localhost:10000/default
!connect jdbc:hive2://localhost:10000/default
Connecting to jdbc:hive2://localhost:10000/default
Connected to: Hive (version 0.10.0)
Driver: Hive (version 0.10.0-SNAPSHOT)
Transaction isolation: TRANSACTION_REPEATABLE_READ
0: jdbc:hive2://localhost:10000> show tables;

我们项目在使用的过程中，因为整合了Hamza的权限控制，使用的时候需要传入用户名和密码，（常用的方式有单次查询-e，也可以把命令写到一个文件中-f），远程连接到HiveServer2：

beeline -u "jdbc:hive2://hadoop1:10000/hamza_group_1" --hivevar hamza.usr="hamza_group" --hivevar hamza.passwd="hMyLXJ6uddQSy1WU" --color=true;

退出beeline命令行则是!quit, 很多命令都是前面需要加一个感叹号，但对于登录了后的DDL,DML，则直接运行SQL语句即可，语句后带上一个分号，然后回车执行。

The maximum column width, in characters, when outputformat is table. Default is 15.
Usage: beeline --maxColumnWidth=25
--maxWidth=MAXWIDTH
