> 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.
