Alan Gates commented on PIG-1627: --------------------------------- The problem is in the flatten, not the group. The group has the proper schema (bytearray, bag{}). Loading a bag of unknown schema and flattening it produces the same result. Flattening a tuple of unknown content has the same problem as well. > Flattening of bags with unknown schemas produces wrong schema > ------------------------------------------------------------- > > Key: PIG-1627 > URL: https://issues.apache.org/jira/browse/PIG-1627 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.7.0 > Reporter: Alan Gates > Assignee: Alan Gates > Fix For: 0.9.0 > > > The following should produce an unknown schema: > {code} > A = load '/Users/gates/test/data/studenttab10'; > B = group A by $0; > C = foreach B generate flatten(A); > describe C; > {code} > Instead it gives > {code} > C: {bytearray} > {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
