Prasad Chakka commented on HADOOP-4070:
---------------------------------------
You are correct that we do need to preppend file:// to files specified in
session parameter hive.aux.jars.path. But what I meant is that instead of
removing the code snippet in ExecDriver, we should mimic what
GenericCommandOptionParser does (possibly refactoring the code out). This would
be proper if user keeps changing this variable between queries. Another option
would be to mandate specification of file:// in the hive.aux.jars.path param
itself. But i prefer the former.

> UDFs (user defined functions) in Hive are currently actually built-in
> functions. This issue is to develop a packaging and registration mechanism so
> users can add their own functions at runtime.
