未来替换hive脚本的最新使用方式。
HiveServer2提供了一个新的命令行工具Beeline，它是基于SQLLine CLI的JDBC客户端。关于SQLLine的的知识，可以参考这个网站：http://sqlline.sourceforge.net/#manual
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。
Beeline Example
% bin/beeline Hive version 0.11.0-SNAPSHOT by Apache beeline> !connect jdbc:hive2://localhost:10000 scott tiger!connect jdbc:hive2://localhost:10000 scott tiger Connecting to jdbc:hive2://localhost:10000 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; show tables; +-------------------+ | tab_name | +-------------------+ | primitives | | src | | src1 | | src_json | | src_sequencefile | | src_thrift | | srcbucket | | srcbucket2 | | srcpart | +-------------------+ 9 rows selected (1.079 seconds)
或者从系统出读取文件
You can also specify the connection parameters on command line. This means you can find the command with the connection string from your UNIX shell history.
% beeline -u jdbc:hive2://localhost:10000/default -n scott -w password_file Hive version 0.11.0-SNAPSHOT by Apache Connecting to jdbc:hive2://localhost:10000/default
