這篇文章給大家分享的是有關Hive CLI beeline是什么的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。
未來替換hive腳本的最新使用方式。
HiveServer2提供了一個新的命令行工具Beeline，它是基于SQLLine CLI的JDBC客戶端。關于SQLLine的的知識，可以參考這個網站：http://sqlline.sourceforge.net/#manual
Beeline工作模式有兩種，即本地嵌入模式和遠程模式。嵌入模式情況下，它返回一個嵌入式的Hive（類似于Hive CLI）。而遠程模式則是通過Thrift協議與某個單獨的HiveServer2進程進行連接通信。
% 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)
或者從系統出讀取文件
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
