[~julianhyde],

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.I opened a new issure to disccuss it, please see
