Doug Cutting commented on HADOOP-3854:
--------------------------------------

> The filter mapping will solve the problem.

But shouldn't the filter mapping be done in Hadoop, not by the application, so that when, e.g., we restructure Hadoop's urls, applications that use this feature don't have to be updated?  Folks could specify an authentication filter that's called for user-facing pages.  That seems like a much easier API for Hadoop to maintain compatibly.

> Filters provide universal functions such as authentication, logging and auditing, etc.  HttpServer should support configurable filters, so that individual site administrators could possibly configure filters for their web site.
