> I extended the native enummerable implemention of calcite to support Hive sql ,include UDF、UDAF and all the SqlSpecialOperator,which inspired by apache Drills.
> I modified the parser,type systems,and bridge the hive operator .
> How do you think of supporting a direct implemention of hive sql like this?
> I think it will be valueable when someone want to migrate his hive etl jobs to real-time scene.
