Hi,
In Hive+parquet, auto type promotion (short->int->bigint) is not supported. Few 
questions:
1. Does Parquet support this type of auto type widening?
2. is it being supported in pig or any similar project?


I'm considering this  for Hive. Other data-formats already support this in 
Hive. ORC recently added the support as well.
I'm not expert in Parquet.

Can someone please give some idea? Some relevant pointers? 
One dev tried it (https://issues.apache.org/jira/browse/HIVE-6784), but could 
not push due to performance ground.

Regards,
Mohammad
