Hive Beeline使用

 Hive Beeline使用

http://blog.csdn.net/huanggang028/article/details/44591663

HiveServer2提供了一個新的命令行工具Beeline，它是基於SQLLine CLI的JDBC客戶端。關於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（類似於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。

下面給一個簡單的登錄Beeline的使用實例：

 

% 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;
show tables;

| src_sequencefile  |

| srcbucket         |
| srcbucket2        |
| srcpart           |
+-------------------+

我們項目在使用的過程中，因為整合了Hamza的權限控制， 使用的時候需要傳入用戶名和密碼，（常用的方式有單次查詢-e，也可以把命令寫到一個文件中-f），遠程連接到HiveServer2：

 

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

退出beeline命令行則是!quit, 很多命令都是前面需要加一個感嘆號， 但對於登錄了后的DDL,DML，則直接運行SQL語句即可，語句后帶上一個分號，然后回車執行。

Icon
Only a single command per -e option is supported. You can't provide multiple semicolon separated commands. Use the -e option multiple times if you want to achieve this.
