In the Apache Pig documentation, it is mentioned that we can define a UDF as both Algebraic and Accumulator http://pig.apache.org/docs/r0.11.1/udf.html#accumulator-interface 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?
