Folks at Hortonworks told me that Hive now uses Calcite as well.  Can anyone here confirm or

Optiq(now known as calcite) is an api for query parser,planner and optimization, drill uses
it for the SQL parsing,validation and optimization.Drill query planner applies its own custom
planner rules to build the query logical plan.
