What do you mean by "username lookup" here?
{quote}
{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.

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.
