Description

The HDFS permissions guide still refers to dfs.web.ugi, and there are some vestiges in the code, but it no longer works post-security.

We should either remove the vestiges entirely and document the servletfilter approach to securing the web UI, or preferably, we could make the StaticUserWebFilter (HADOOP-6832) respect this configuration parameter (possibly with deprecation).
