      Work Description: pvary opened a new pull request #2137:
URL: https://github.com/apache/hive/pull/2137


   ### What changes were proposed in this pull request?
   There are 3 parts of the changes here:
   - Pruner changes to provide a filter instead of changing the file lists
   - HiveInputFormat changes to combine the Pruning filter with the original filter
   - Iceberg handler changes:
      - New method in SerDe to return the current partitioning columns
      - HiveStoragePredicateHandler implements the addDynamicSplitPruningEdge method which returns true if there is a filter for any of the partitioning columns
   - Added new test for partition pruning
   
   ### Why are the changes needed?
   To archive comparable performance for Iceberg tables
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   Multiple queries
   
   Plan to add more tests later, but it would be good to have them as a `qtest` and it should be done in a different PR as it is a sizable task in itself
