添加mysql-connector.jar in $SQOOP_HOME/lib。

按Sqoop docs，

您可以使用Sqoop与其他任何符合JDBC的数据库。首先，下载相应的JDBC驱动程序要导入数据库的类型，和您的客户端机器

而且上安装.jar文件中$SQOOP_HOME/lib目录，

每个驱动.jar文件也有一个特定的驱动程序类，它定义了驱动程序的入口点。例如，MySQL的Connector/J库的驱动程序类别为com.mysql.jdbc.Driver。请参阅您的数据库供应商特定的文档以确定主要的驱动程序类。此类必须作为Sqoop的参数提供，并使用--driver。

因此，在您的命令中添加--driver com.mysql.jdbc.Driver。
