Description

Currently, column name in parquet is case-sensitive, which is different from SQL where query is case-insensitive.

For instance, the following query will fail on drill:
Select _MAP['n_name'] AS N_NAME from "nation";

The following query is fine:
Select _MAP['N_NAME'] AS N_NAME from "nation";

If we want to follow SQL, then it would be nice to make parquet column name case-insensitive as well.
