Santhosh Srinivasan reassigned PIG-538: --------------------------------------- Assignee: Pradeep Kamath (was: Santhosh Srinivasan) > bincond can't work with flatten bags > ------------------------------------ > > Key: PIG-538 > URL: https://issues.apache.org/jira/browse/PIG-538 > Project: Pig > Issue Type: Bug > Affects Versions: types_branch > Reporter: Olga Natkovich > Assignee: Pradeep Kamath > Fix For: types_branch > > > The following script is user with trunk code to simulated outer join not > directly supported by pig: > A = load '/studenttab10k' as (name: chararray, age: int, gpa: float); > B = load 'votertab10k' as (name: chararray, age: int, registration: > chararray, donation: float); > C = cogroup A by name, B by name; > D = foreach C generate group, (IsEmpty(A) ? '' : flatten(A)), (IsEmpty(B) ? > 'null' : flatten(B)); > On types branch this gives syntax error and even beyond that not supported > since bincond requires that both expressions be of the same type. Santhosh > suggested to have special NULL expression that matches any type. This seems > to make sense. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
