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 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.
