Description

Pig accepts a macro like:

define COUNT(in_relation, min_gpa) returns c {
                           b = filter $in_relation by gpa >= $min_gpa;
                           $c = foreach b generate age, name;
                       }

This should produce a warning that it is masking a UDF.
