----------------------------------

             Summary: Refactor Partition Pruner so that logic can be reused.
                 Key: HIVE-3514
                 URL: https://issues.apache.org/jira/browse/HIVE-3514
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Gang Tim Liu
            Assignee: Gang Tim Liu
            Priority: Minor


Partition Pruner has logic reusable like

1. walk through operator tree
2. walk through operation tree
3. create pruning predicate

The first candidate is list bucketing pruner.

Some consideration:
1. refactor for general use case not just list bucketing
2. avoid over-refactor by focusing on pieces targeted for reuse
