Question:java HTTPFS : giving error “User: ubuntu is not allowed to impersonate ubuntu” while accessing the application through Http

I have installed hadoop 1.0.4 on my cluster, of 1 master and 3 slaves, and now I am installing HTTPFS(hadoop-hdfs-httpfs-0.20.2-cdh3u5-SNAPSHOT) to access the HDFS contents using http protocol,

I am able to access the normal page through it

curl -i "http://myhost:14000"

its works fine :)

but If I tried to access HDFS then its giving me error(ubantu is my user) :(

curl -i "http://myhost:14000/webhdfs/v1?"


    {"RemoteException":{"message":"User: ubantu is not allowed to impersonate ubantu",

Thanks in advance.
