这个问题很明显是我linux和window的mysql连接出错，和我的sqoop命令：sqoop list-databases --connect jdbc:mysql://master:3306/ --username root -P没有关系的
首先想到的是windows本地mysql的权限问题，因此首先在window是打开mysql发现我的mysql运行正常，然后执行命令：
grant all privileges on . to root@master identified by '123456';
生效命令：flush privileges;

再输入刚才的命令，就可以开心的访问数据库了
