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

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.
