Subject [jira] Created: (PIG-973) type resolution inconsistency
Date Wed, 23 Sep 2009 00:25:16 GMT
type resolution inconsistency
-----------------------------

                 Key: PIG-973
                 URL: https://issues.apache.org/jira/browse/PIG-973
             Project: Pig
          Issue Type: Bug
            Reporter: Olga Natkovich


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.
