這篇文章給大家分享的是有關(guān)Hive CLI beeline是什么的內(nèi)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。

我們一直強調(diào)成都網(wǎng)站設(shè)計、網(wǎng)站制作、外貿(mào)營銷網(wǎng)站建設(shè)對于企業(yè)的重要性,如果您也覺得重要,那么就需要我們慎重對待,選擇一個安全靠譜的網(wǎng)站建設(shè)公司,企業(yè)網(wǎng)站我們建議是要么不做，要么就做好,讓網(wǎng)站能真正成為企業(yè)發(fā)展過程中的有力推手。專業(yè)網(wǎng)站建設(shè)公司不一定是大公司,創(chuàng)新互聯(lián)作為專業(yè)的網(wǎng)絡(luò)公司選擇我們就是放心。

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(guān)于SQLLine的的知識，可以參考這個網(wǎng)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(xié)議與某個單獨的HiveServer2進程進行連接通信。

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      |

| src1              |
| src_json          |

或者從系統(tǒng)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

--autoCommit=[true/false]

Enable/disable automatic transaction commit. Default is false.

Usage: beeline --autoCommit=true

Usage: beeline --maxColumnWidth=25

--silent=[true/false]

Reduce the amount of informational messages displayed (true) or not (false). It also stops displaying the log messages for the query from HiveServer2 (Hive 0.14 and later) and the HiveQL commands (Hive 1.2.0 and later). Default is false.

Usage: beeline --silent=true

--autosave=[true/false]

Automatically save preferences (true) or do not autosave (false). Default is false.

--incremental=[true/false]

Defaults to false. When set to false, the entire result set is fetched and buffered before being displayed, yielding optimal display column sizing. When set to true, result rows are displayed immediately as they are fetched, yielding lower latency and memory usage at the price of extra display column padding. Setting --incremental=true is recommended if you encounter an OutOfMemory on the client side (due to the fetched result set size being large).

--help

Display a usage message.

Usage: beeline --help
