optimizations pig is doing under the hood.
I was actually trying to answer my own question using EXPLAIN and avoid
sending a request to the list :-P
The biggest problem I can see is that terminology used in explain isn't
documented anywhere and I think it's mostly intended for advanced pig
developers (not users).
LOInnerLoad….. this isn't documented anywhere except the source code.
Also, New For Each(false,false) ……
What do false and false mean? Maybe include the variable names or a
description of the variables?
Right now I think EXPLAIN should probably be renamed to CONFUSE :-P
