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