hive UDFs with distributed cache

Is it possible to write a hive UDF that has an access to distributed cache
OR a way to look up information from a file in an evaluate function?
Are there any examples around?

Thanks,
Abhi

Hey Abhi,
You could drop into MapReduce and do the access to DistributedCache using
the standard Java APIs. There may be a cleaner way, but that should be
possible.

Regards,
Jeff
