Description

This script works:

A = load 'test' using PigStorage(':') as (name: chararray, age: int, gpa: float);
B = group A by age;
C = foreach B

{ D = filter A by gpa > 2.5; E = order A by name; F = A.age; describe F; G = distinct F; generate group, COUNT(D), MAX (E.name), MIN(G.$0);}

dump C;

This one produces an error:

A = load 'test' using PigStorage(':') as (name: chararray, age: int, gpa: float);
B = group A by age;
C = foreach B

{ D = filter A by gpa > 2.5; E = order A by name; F = A.age; G = distinct F; generate group, COUNT(D), MAX (E.name), MIN(G);}

dump C;

Notice the difference in how MIN is passed the data.
