Thejas M Nair commented on PIG-1636: ------------------------------------ +1 > Scalar fail if the scalar variable is generated by limit > -------------------------------------------------------- > > Key: PIG-1636 > URL: https://issues.apache.org/jira/browse/PIG-1636 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.8.0 > Reporter: Daniel Dai > Assignee: Daniel Dai > Fix For: 0.8.0 > > Attachments: PIG-1636-1.patch > > > The following script fail: > {code} > a = load 'studenttab10k' as (name: chararray, age: int, gpa: float); > b = group a all; > c = foreach b generate SUM(a.age) as total; > c1= limit c 1; > d = foreach a generate name, age/(double)c1.total as d_sum; > store d into '111'; > {code} > The problem is we have a reference to c1 in d. In the optimizer, we push > limit before foreach, d still reference to limit, and we get the wrong schema > for the scalar. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
