Richard Ding commented on PIG-973: ---------------------------------- This following script also produces an error: {code} A = load 'input' as (id:int, g:bag{t:tuple(u:int)});; B = foreach A generate id, SUM(g); ; dump B; {code} The problem appears to be with the patch of PIG-315, which only pushed the exception from compile-time to runtime for the script below: {code} a = load 'studenttab10k' as (name:chararray, age:int, gpa:double); b = foreach a generate (long)age as age, (int)gpa as gpa; c = foreach b generate SUM(age), SUM(gpa); dump c; {code} Actually, one can argue that this is an invalid script -- the input type of the eval function SUM is a bag of numbers, not a number. So it should be caught at compile-time (by the parser if posible). > type resolution inconsistency > ----------------------------- > > Key: PIG-973 > URL: https://issues.apache.org/jira/browse/PIG-973 > Project: Pig > Issue Type: Bug > Reporter: Olga Natkovich > Assignee: Richard Ding > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
