I got the same problem with hadoop 2.8.3 and eclipse Mars. I solved the problem according to this blog: http://blog.csdn.net/l1028386804/article/details/52665022.

hadoop fs -mkdir /Administrator

change 'Administrator' to your username.

@junsionzhang I'm sorry to see it now.
Yes, tested. You can download it from here: http://download.csdn.net/download/familyshizhouna/10172755
