Excuse my naive question, however, it seems that this does not use the
regular Hive UDF API, right? (Like when I would run `hiveContext.sql("CREATE
TEMPORARY FUNCTION [...]")` ). Is there any particular reason for that? I
noticed, that UDFs created using this mechanism won't show up in the `SHOW
FUNCTIONS` list. Would it be difficult to achieve that?
Also, the Hive API allows to add description strings to a UDF (which
obviously only makes sense if you can use `DESCRIBE FUNCTION`). It would be
nice if something similar would exists for UDFs defined over the spark
interface.
