这个属于通信问题，
检查防火墙
检查集群是否开启等。

下面也是中解决方案
原因：本地用户administrator（本机windows用户）想要远程操作hadoop系统，没有权限引起的。
解决办法：
1、如果是测试环境，可以取消hadoop hdfs的用户权限检查。打开conf/hdfs-site.xml，找到dfs.permissions属性修改为false（默认为true）OK了。（1.2.1 版本只有这个方法可行），如何操作可以参考第一个问题。
2、修改hadoop location参数，在advanced parameter选项卡中，找到hadoop.job.ugi项，将此项改为启动hadoop的用户名即可
3 修改window 机器的用户名为 hadoop 用户名。
