sqoop将hive里的表导入mysql

sqoop 导出hive数据到mysql   执行命令

bin/sqoop export --connect jdbc:mysql://slaver3:3306/ishangzu --username root --password root --table dw_pv_uv_ip --export-dir /user/hive/warehouse/t_20161019.db/dw_pv_uv_ip/datestr=20161019 --input-fields-terminated-by '\001'

报如下错误：

问题本质：基于安全考虑root账户一般只能本地访问，但是在开发过程中可能需要打开root的远程访问权限。下面是基本的步骤：

登录到mysql中，为root进行远程访问的授权，执行下面的命令： 

mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";

mysql> flush privileges;

 

执行完上面的操作后，即可
