Change subject: PREVIEW do parquet schema resolution by name instead of ordinal ...................................................................... PREVIEW do parquet schema resolution by name instead of ordinal This patch introduces a new query option, RESOLVE_PARQUET_BY_NAME, which makes Parquet files' schemas be resolved by name instead of ordinal. The default is still by ordinal. I chose to do a query option because it will make testing easier and also be easier to diagnose resolution problems quickly in the field. If users want to switch the default behavior to be by name (like Hive), they can use the --default_query_options flag.
