我正在尝试将 Sqoop 与 Mysql 连接起来。在问这个问题之前，我尝试了所有我搜索过的解决方案，但都没有奏效。
这就是我正在输入的内容
/usr/local/hadoop/sqoop/lib$ sqoop 列表数据库 --connect jdbc:mysql://localhost:3306/testDb --用户名 Amel --密码 > Amel@-1998;
我确实在 /usr/local/hadoop/Sqoop/lib/ 目录中安装了 SQLConnector。
它的名字是：mysql-connector-java_8.0.25-1ubuntu20.04_all.deb 我已经安装了.deb 文件
这是每次都会出现的错误。
