-Re: Decide if function is algebraic at planning phase

Out of curiosity: what for? Algebraic works faster in most cases.
1) Maybe you can disable the use of combiner or something else that is
related. Maybe if you change the Configuration to
that will disable the use of Algebraic, but I am not sure, that's just a thought
2) You can embed pig into Java or Python from where you can construct
pig scripts pro grammatically, using the appropriate UDF
