> Under simple auth, UGI identifies the current Hadoop user as the OS user. If
> the OS can't determine the user, then they receive a cryptic
> {{KerberosAuthException}}, even though Kerberos auth isn't really configured.
> I've seen this come up for Hadoop processes launched in Docker containers
> that accidentally specify a UID that's not actually present in the image. We
> can improve this error so that users have a better understanding of how to
> fix the problem.
