Hi, Narayanan:
The current problem is that for a generic solution, there is no way that we

Thanks Peyman.
Actually the problem with Hive-Json-Serde is that we need to provide
the entire schema upfront while creating the table.
My requirement is that we just project/aggregate on the fields using
get_json_object after creating the external table without schema. This
way the external
