-----------------------------------
It will take some time to merge my modifications based on calcite 1.17.0 into
the master branch , I will add a new module "hive" of the project ,which
includes tests of my use case .Afterwards,I will submit the PR.
> Add operator table with Hive-specific built-in functions

> [~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.
