sqoop ERROR manager.CatalogQueryManager: Failed to list databases java.sql.SQLException: Access deni

困扰了我一天的巨坑问题！原因很简单！修改IP！

在用sqoop连接Mysql查看Mysql数据库报错：

我使用的是此命令：

sqoop list-databases --connect jdbc:mysql://127.0.0.1:3306/ --username root -P

**

划重点！！！！

**
因为连接的是主机Mysql，所以命令中的IP应该改为自己主机IP
如：
我的主机IP：

输入代码时就应该修改成如下命令：

sqoop list-databases --connect jdbc:mysql://192.168.43.100:3306/ --username root -P

运行！查看结果！完美解决！
