What do you mean by "username lookup" here?

{code}
+      this.username = conf.getInitParameter(USERNAME_KEY);
+      this.user = new User(username);
{code}
I agree it isn't huge, which is why I left it in, but it also isn't adding any value.

The same could be said for every other default throughout all of common, HDFS, and MR, no?
{quote}

No, actually. We do it in a lot of places, but it leads to lots of confusion. Furthermore,
this isn't a framework default, but a plugin default. I don't think it is appropriate to put
into the default configuration file.

{quote}
Apparently most of our very-confused customers who've filed tickets about this don't agree.

The issue isn't the default value of "dr.who". Having a magic value of "webuser" will have
*exactly* the same problem with trying to figure out where it is coming from. Furthermore,
if they *actually* have a real *webuser* account, it could create problems. I guess we could
use "default.web.user" or something.

> We need a simple plugin that uses a static user for clusters with security that don't
want to authenticate users on the web UI.
