------------------------------------
[~Prabhu Joseph] If I am reading patch 5 code correctly, this will ignore both
AuthenticationFilter, and also ProxyUserAuthenticationFilter. Is there another
code path that is used to ensure ApplicationHistoryServer is protected?

Is there any way to make the initialization code more straight forward?

> In the enclosed spreadsheet, it shows the list of web applications deployed
> by Hadoop, and filters applied to each entry point.
> Hadoop web protocol impersonation has been inconsistent. Most of entry point
> do not support ?doAs parameter. This creates problem for secure gateway like
> Knox to proxy Hadoop web interface on behave of the end user. When the
> receiving end does not check for ?doAs flag, web interface would be accessed
> using proxy user credential. This can lead to all kind of security holes
> using path traversal to exploit Hadoop.
> In HADOOP-16287, ProxyUserAuthenticationFilter is proposed as solution to
> solve the web impersonation problem. This task is to track changes required
> in Hadoop code base to apply authentication filter globally for each of the
> web service port.
