Hi Min, Hive does not have that capability right now. The reason is that Hive does not copy the jars that contains user registered UDFs.
However, if we can keep the jars at a safe place, it shouldn't be hard to modify hive client side (bin/hive) to load all the UDFs from the jars before the hive client side starts.
