HBase and Sqoop Integrated Case

Sqoop integration with HBase

Case: The extracted data in an RDBMS to HBase

STEP . 1 , arranged Sqoop -env.sh follows:

 

The STEP 2 , create a database library in Mysql in a table book

CREATE DATABASE library;

CREATE TABLE book(

id int(4) PRIMARY KEY NOT NULL AUTO_INCREMENT,

name VARCHAR(255) NOT NULL,

price VARCHAR(255) NOT NULL);

STEP . 3 , insert some data into the table

INSERT INTO book(name, price) VALUES('Lie Sporting', '30');  

INSERT INTO book (name, price) VALUES('Pride & Prejudice', '70');  

INSERT INTO book (name, price) VALUES('Fall of Giants', '50');  

After the completion of Figure:

 

STEP . 4 , data import operation is performed Sqoop

$ bin/sqoop import \

--connect jdbc:mysql://hadoop-senior01.itguigu.com:3306/db_library \

--username root \

--password 123456 \

--table book \

--columns "id,name,price" \

--column-family "info" \

--hbase-create-table \

--hbase-row-key "id" \

--hbase-table "hbase_book" \

--num-mappers 1  \

--split-by id

Step5、在HBase中scan这张表得到如下内容

 

（尖叫提示：在导入之前，HBase中的表如果不存在则会自动创建）
