Jason Dere updated HIVE-6167:
-----------------------------
Attachment: HIVE-6167.1.patch
Initial patch. Since built-in/temp functions do not have qualifiers there isn't
won't actually be any functions that are resolvable when qualified with a db
name, but this does allow Hive to parse qualified function names.
> Allow user-defined functions to be qualified with database name

> Function names in Hive are currently unqualified and there is a single
> namespace for all function names. This task would allow users to define
> temporary UDFs (and eventually permanent UDFs) with a database name, such as:
> CREATE TEMPORARY FUNCTION userdb.myfunc 'myudfclass';
