Lefty Leverenz commented on HIVE-14100:
---------------------------------------

Doc note:  The new UDF logged_in_user() needs to be documented in the wiki for release 2.2.0.

Added a TODOC2.2 label.

> There is an existing current_user() UDF which returns the user provided by the configured
{{hive.security.authenticator.manager}}. This is often the same as the user provided on connection,
but some cases, like HadoopDefaultAuthenticator this could be different.
> Some cases we need the logged in user independently of the configured authenticator,
so a new UDF is created which provides this - returns the {{SessionState.get().getUserName()}}.
