[jira] [Created] (HIVE-17109) Remove calls to RelMetadataQuery.instance() after Calcite 1.13 upgrade

Remus Rusanu created HIVE-17109:
-----------------------------------

             Summary: Remove calls to RelMetadataQuery.instance() after Calcite 1.13 upgrade
                 Key: HIVE-17109
                 URL: https://issues.apache.org/jira/browse/HIVE-17109
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Remus Rusanu
            Assignee: Remus Rusanu


After CALCITE-1812 the code should retrieve the RelMetadataQuery from the planner, if needed. Calling {{RelMetadatQuery.instance()}} invalidates the Calcite RelNode properties memoization cache.
