04 使用Sqoop将mysql数据导入hbase

Posted 2023-03-27

参考技术A 本节演示使用Sqoop将mysql数据导入hbase。

（1）mysql数据导入hbase

如此，就完成了把mysql导入了hbase。

使用sqoop将MySQL数据库中的数据导入Hbase

使用sqoop将MySQL数据库中的数据导入Hbase

前提：安装好 sqoop、hbase。

下载jbdc驱动：mysql-connector-java-5.1.10.jar

将 mysql-connector-java-5.1.10.jar 拷贝到 /usr/lib/sqoop/lib/ 下

MySQL导入HBase命令：
sqoop import --connect jdbc:mysql://10.10.97.116:3306/rsearch --table researchers --hbase-table A --column-family person --hbase-row-key id --hbase-create-table --username \'root\' -P

说明：
--connect jdbc:mysql://10.10.97.116:3306/rsearch 表示远程或者本地 Mysql 服务的URI，3306是Mysql默认监听port，rsearch是数据库，若是其它数据库，如Oracle,仅仅需改动URI就可以。

--table researchers  表示导出rsearch数据库的researchers表。

--hbase-table A  表示在HBase中建立表A。

--column-family person 表示在表A中建立列族person。
--hbase-row-key id  表示表A的row-key是researchers表的id字段。
--hbase-create-table 表示在HBase中建立表。
--username \'root\' 表示使用用户root连接Mysql。

注意：

HBase的全部节点必须可以訪问MySQL数据库。不然会出现例如以下错误：
java.sql.SQLException: null,  message from server: "Host \'10.10.104.3\' is not allowed to connect to this MySQL server"

[plain] view plaincopy

1. 在MySQL数据库server节点上运行下面命令同意远程机器使用对应用户訪问本地数据库server：  
2. [root@gc01vm6 htdocs] # /opt/lampp/bin/mysql  
3.   
4. mysql> use mysql;  
5. Database changed  
6. mysql> GRANT ALL PRIVILEGES ON rsearch.* TO \'root\'@\'10.10.104.3\' IDENTIFIED BY \'\' WITH GRANT OPTION;   
7. mysql> GRANT ALL PRIVILEGES ON rsearch.* TO \'root\'@\'10.10.104.5\' IDENTIFIED BY \'\' WITH GRANT OPTION;   
8. mysql> GRANT ALL PRIVILEGES ON rsearch.* TO \'root\'@\'10.10.104.2\' IDENTIFIED BY \'\' WITH GRANT OPTION;   

这里10.10.104.2，10.10.104.3，10.10.104.5 是HBase节点。
