Daniel Dai updated PIG-1127: ---------------------------- Attachment: PIG-1127-2.patch > Logical operator should contains individual copy of schema object > ----------------------------------------------------------------- > > Key: PIG-1127 > URL: https://issues.apache.org/jira/browse/PIG-1127 > Project: Pig > Issue Type: Bug > Affects Versions: 0.4.0 > Reporter: Daniel Dai > Assignee: Daniel Dai > Fix For: 0.6.0 > > Attachments: PIG-1127-1.patch, PIG-1127-2.patch > > > Currently some logical operator only contains a schema reference to the > predecessor's schema object. These logical operators include: LOSplitOutput, > LOLimit, LOSplit, LOFilter, LOSort, LODistinct, LOUnion. It is ok in the > before because we do not change schema object once it is set. Now with the > column pruner (PIG-922), we need to change individual schema object so it is > no longer acceptable. For example, the following script fail: > {code} > a = load '1.txt' as (a0, a1:map[], a2); > b = foreach a generate a1; > c = limit b 10; > dump c; > {code} > We need to fix it. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
