> Currently, parquet tables, like other filesystem tables, are treated as schema-less tables. But it would make sense to get the schema by reading and merging the footers from all of the parquet files. This will allow drill to validate whether a requested column exists, and throw an error before running the query. It will also remove the need to qualify columns with the table name or alias when doing a join.
