http call when no authorization is sent throws a 401 with no error resonse
--------------------------------------------------------------------------
Key: HADOOP-7812
URL: https://issues.apache.org/jira/browse/HADOOP-7812
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.20.205.0
Reporter: Arpit Gupta
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.
