The client component is the AuthenticatedURL class. The server component is the AuthenticationFilter servlet filter class. Authentication mechanisms support is pluggable in both the client and the server components via interfaces. In addition to Kerberos SPNEGO, Hadoop Auth also supports Pseudo/Simple authentication (trusting the value of the query string parameter 'user.name').
