> As discussed in HADOOP-9797, it would be better to improve UGI incrementally. Open this JIRA to improve User class to:
> * Make it extensible as a base class, then can have subclasses like SimpleUser for Simple authn, KerberosUser for Kerberos authn, IdentityTokenUser for TokenAuth (in future), and etc.
> * Decouple it from Kerberos.
> * Refactor UGI class safely, move testing related codes out of it.
