解决方法：

　　到服务器上修改hadoop的配置文件：conf/hdfs-core.xml, 找到 dfs.permissions 的配置项 , 将value值改为 false

dfs.permissions
false

If "true", enable permission checking in HDFS.
If "false", permission checking is turned off,
but all other behavior is unchanged.
Switching from one parameter value to the other does not change the mode,
owner or group of files or directories.

修改完貌似要重启下hadoop的进程才能生效
