Lai Zhou updated CALCITE-2741:
------------------------------
Description:
[~julianhyde],
I write a hive adapter for calcite to support Hive sql ,includes UDF、UDAF、UDTF
and some of SqlSpecialOperator.
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.

[~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.
