> 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.
