If a custom authentication mechanism is required for the HTTP web-consoles, it is possible
to implement a plugin to support the alternate authentication mechanism (refer to
Hadoop Alfredo for details on writing an <code>AuthenticatorHandler</code>).
Hadoop hadoop-auth for details on writing an <code>AuthenticatorHandler</code>).
