> Problems with partition filter optimizer
> ----------------------------------------
>
> Key: PIG-1267
> URL: https://issues.apache.org/jira/browse/PIG-1267
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Richard Ding
> Assignee: Richard Ding
> Fix For: 0.7.0
>
> Attachments: PIG-1267.patch
>
>
> There are a couple of problems with the current partition filter optimizer:
> 1. When a partition filter is removed from the logical plan, the input index
> of the following join/cogroup operator may change, which in turn changes the
> ordering of the fields in the schema and results in compile-time errors.
> 2. At most one partition filter can be removed per plan, while multiple
> partition filters can exist in the cases of joins.
