> HttpFs tries to use UserProfile.USER_PATTERN to match all usernames before a
> doAs impersonation function. This regex is too strict for most usernames, as
> it disallows any special character at all. We should relax it more or ditch
> needing to match things there.
> WebHDFS currently has no such limitations.
