-------------------------------
[~prabhujoseph]
I also think this is needed, if we can add an option to support:
We can add an option to allow this two independent,
hadoop.security.authentication is specific to RPC Authentication whereas
hadoop.http.authentication.type is specific to HTTP Authentication.
We want to make HTTP not authentication, but RPC Authentication.
> JspHelper ignores hadoop.http.authentication.type
