Description

We don't want to enable security for viewing namenode http page, but we don't want people to be able to modify the contents of hdfs through anonymous access to the namenode page.  in Hadoop 3 we lost the ability to totally disable webhdfs.  want to bring this back, doesn't seem to hard to do, but makes it important in our environment.
