> 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.
