Alan Gates commented on PIG-3199:
---------------------------------
Even making Operator public is dangerous. These are internal structures.
It would help to understand who you want to expose these to and why. Then we
can see if there's a way to get you the information you need. I don't want to
stand in the way of innovation but I also don't want Pig's internals exposed to
the point that the next time we make a change to our Operator class someone
complains because we broke his tool.

> LogicalPlan could be exposed to user in order for one to make validations
> based on it. For eg, one could get Load/Store paths or other operators and be
