-------------------------------------------
Summary: Drop HiveFilterMergeRule and use FilterMergeRule from
Calcite
Key: HIVE-25974
URL: https://issues.apache.org/jira/browse/HIVE-25974
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 4.0.0
Reporter: Alessandro Solimando
HiveFilterMergeRule is a copy of FilterMergeRule which was needed since the
latter did not simplify/flatten before creating the merged filter.
This behaviour has been fixed in CALCITE-3982 (released since 1.23), so it
seems that the Hive rule could be removed now.
