It uses both. They are not contradictory.

Subject: A UDF that is both Algebraic and Accumulator
In the Apache Pig documentation, it is mentioned that we can define a UDF
as both Algebraic and Accumulator
If I do such a thing, how Pig decides which interface of them to use. I
assume they are completely separate and they cannot be mixed with each
other. Is there a way to enforce Pig to prefer one of them over the other?
