sqoop-从mysql导入数据到hive出现java.sql.SQLException: Streaming result set com.mysql.jdbc.

初学sqoop，按照教程一步步来，我的配置文件里面只配置了hive的路径，并且把hive那边的mysql的驱动包给拿过来了，但是导入数据时出现如下错误：

ERROR manager.SqlManager: Error reading from database: java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@44f16719 is still active. No statements may be issued when
any streaming result sets are open and in use on a given connection. Ensure that you have called .close() on any active streaming result sets before attempting more queries.

经过网上查阅，以及实践，需要把sqoop的lib目录里面的mysql驱动包改成mysql-connector-java-5.1.32-bin.jar，然后重新执行刚才的步骤。ok！

ps:sqoop1.4.6
