解决办法：You need to have a user home directory on HDFS. Log as the HDFS user and create a home dir for root.

# su - hdfs  
$ hdfs dfs -mkdir /user/root  
$ hdfs dfs -chown root:root /user/root

如果已经有了/user/root ，查看下文件的权限

[root@dn001 ~]# hdfs dfs -ls /user

改为root所有：

$ hdfs dfs -chown root:root /user/root
