> Currently if you make an http call to the namenode and do not send any authorization returns 401 as expected but no response content.
> I would be nice if we could return some error response stating that the user provided no authorization. It would make it a little easier for people making the call from a browser to find out if something went wrong.
> curl call
> {code}
> curl -i "http://NN:PORT/webhdfs/v1/tmp/webhdfs_data?op=gethomedirectory"
> HTTP/1.1 401 Unauthorized
> Content-Type: text/html; charset=utf-8
> WWW-Authenticate: Negotiate
> Content-Length: 0
> Server: Jetty(6.1.26)
> {code}
