John Sichi commented on HIVE-2561:
----------------------------------
@Ed: the standard SQL way to handle this is via SQL/J jar support (as
implemented by Oracle, PostgreSQL, DB/2, LucidDB, and others). There, you
bundle up the function descriptions inside of a descriptor file in the jar, and
then when you add the jar to the system, all of the functions get deployed
automatically. And there's a way to declare dependencies between jars as well.
Long-term, we could consider adding that as part of support for persistent
functions; the whole temporary function thing is kludgy to begin with (in my
opinion), so a little more won't kill us in the interim.

> Often times UDFs will have dependencies to external JARs/FILEs. It makes
> sense for these to be encoded by the UDF (rather than having the caller
> remember the set of files that need to be ADDed). Let's add an annotation to
> UDFs which will cause these resources to be auto-added.
