Description
HIVE-21231 caused the pattern of scalar subqueries to change a bit causing HiveRemoveSqCountCheck rule to not kick in anymore.
Queries for which this has regressed are the ones which contain group by with constant keys. getRelMdMaxRowCount needs to be improved for this to work.
Ref: CALCITE-2991
