Dmitriy V. Ryaboy commented on PIG-1292:
----------------------------------------
.. but we have an abstract class that can provide default implementations so
that implementers don't have to think about this.
Most of the interfaces introduced in PIG-966 have significant chunks of
functionality associated with them. This is just a single method about a
particular property of the incoming data.
I can see why you'd be against putting it into LoadFunc, though, as it's very
specific. What about ResourceSchema or LoadMetaData?
