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 复制到 /usr/lib/sqoop/lib/ 下
MySQL导入HBase命令：
sqoopimport--connectjdbc:mysql://10.10.97.116:3306/rsearch--tableresearchers--hbase-tableA--column-familyperson--hbase-row-keyid--hbase-create-table--username'root'-P
说明：
--connectjdbc:mysql://10.10.97.116:3306/rsearch表示远程或者本地Mysql服务的URI，3306是Mysql默认监听端口，rsearch是数据库，若是其他数据库，如Oracle,只需修改URI即可。
--tableresearchers表示导出rsearch数据库的researchers表。
--hbase-tableA表示在HBase中建立表A。
--column-familyperson表示在表A中建立列族person。
--hbase-row-keyid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的所有节点必须能够访问MySQL数据库，不然会出现如下错误：
java.sql.SQLException: null, message from server: "Host '10.10.104.3' is not allowed to connect to this MySQL server"- 在MySQL数据库服务器节点上执行以下命令允许远程机器使用相应用户访问本地数据库服务器：
- [root@gc01vm6 htdocs] # /opt/lampp/bin/mysql
- mysql> use mysql;
- Database changed
- mysql> GRANT ALL PRIVILEGES ON rsearch.* TO 'root'@'10.10.104.3' IDENTIFIED BY '' WITH GRANT OPTION;
- mysql> GRANT ALL PRIVILEGES ON rsearch.* TO 'root'@'10.10.104.5' IDENTIFIED BY '' WITH GRANT OPTION;
- mysql> GRANT ALL PRIVILEGES ON rsearch.* TO 'root'@'10.10.104.2' IDENTIFIED BY '' WITH GRANT OPTION;
在MySQL数据库服务器节点上执行以下命令允许远程机器使用相应用户访问本地数据库服务器：[root@gc01vm6 htdocs] # /opt/lampp/bin/mysqlmysql> use mysql;Database changedmysql> GRANT ALL PRIVILEGES ON rsearch.* TO 'root'@'10.10.104.3' IDENTIFIED BY '' WITH GRANT OPTION; mysql> GRANT ALL PRIVILEGES ON rsearch.* TO 'root'@'10.10.104.5' IDENTIFIED BY '' WITH GRANT OPTION; 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。
