用sqoop导入mysql数据出现以下错误：
14/12/03 16:37:58 ERROR manager.SqlManager: Error reading from database: java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@54b0a583 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.

这个是由于mysql-connector-java的bug造成的，出错时我用的是mysql-connector-java-5.1.10-bin.jar，更新成mysql-connector-java-5.1.32-bin.jar就可以了。mysql-connector-java-5.1.32-bin.jar的下载地址为http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.32.tar.gz。下载完后解压，在解压的目录下可以找到mysql-connector-java-5.1.32-bin.jar。
