org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException)

在运行hadoop的程序时，向hdfs中写文件时候，抛出异常信息如下：

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=Administrator, access=WRITE, inode="/user":root:supergroup:drwxr-xr-x

原因：Hdfs中的/user目录是属于supergroup组里的root用户的。解决办法：方法一：换成root用户解决问题。方法二：将当前用户添加到supergroup组中即可。
