刚入门学习hadoop，然后在sqoop数据迁移这里遇到了问题，linux下使用sqoop连接不上windows系统的MySQL数据库，按照网上的许多方法都没解决。
linux系统是centos6.4，然后hadoop2.4.1，sqoop1.4.7，windows下是mysql5.7
下面是报错信息：
[root@itcast01 bin]# ./sqoop list-tables --connect jdbc:mysql://192.168.147.100:3306/sqoopex1 --username root -password 1234

zookeeper和hadoop服务都开启了的，防火墙也关闭了，去度娘有人说修改my.ini文件，说在[mysqld] 那里加一行： wait_timeout=86400 。 但是我修改后还是报同样的错误。mysql权限也赋予了的。数据库连接驱动使用mysql-connector-5.1.8.jar。
连接的ip地址192.168.147.100是windows的VMnet1的ip地址，能ping通。然后就是连接不上数据库。使用Navicat连接也能连得上。
有没有大牛知道我问题出在哪里？感激不尽！
