Alan Gates reassigned PIG-51: ----------------------------- Assignee: Utkarsh Srivastava > Combiner gives wrong result in the presence of flattening > --------------------------------------------------------- > > Key: PIG-51 > URL: https://issues.apache.org/jira/browse/PIG-51 > Project: Pig > Issue Type: Bug > Reporter: Utkarsh Srivastava > Assignee: Utkarsh Srivastava > Priority: Critical > Fix For: 0.1.0 > > Attachments: combiner-flatten.patch > > > If you do something like > a = load ... as (f1,f2,f3); > b = group a by (f1,f2); > c = foreach b generate flatten(group), SUM(a.f3); > The reduce side refers to field number expecting data will not have been > flattened yet. But if the combiner kicks in, it already flattens the group, > leading to column references being wrong. > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
