[jira] [Created] (HIVE-22408) The fix for CALCITE-2991 creates wrong results on edge case

Steve Carlin created HIVE-22408:
-----------------------------------

             Summary: The fix for CALCITE-2991 creates wrong results on edge case
                 Key: HIVE-22408
                 URL: https://issues.apache.org/jira/browse/HIVE-22408
             Project: Hive
          Issue Type: Bug
          Components: CBO
    Affects Versions: 3.1.2
            Reporter: Steve Carlin
            Assignee: Vineet Garg


The Calcite upgrade from 1.19 to 1.21 includes a fix for CALCITE-2991.  This patch causes a failure in subquery_ALL.q

In order to proceed with the upgrade, the patch was bypassed by creating the HiveRelMdMaxRowCount class which overrides the behavior in Calcite.  

In order to recreate the regression, remove this file and the references to the class in HiveDefaultRelMetadataProvider.

This Jira is being created before the HIVE-22274 PR has been pushed, so please wait until that is pushed before working on this.
