> HIVE-14792 introduces support to modify and add properties to table-parameters during
query-planning. It prefetches remote Avro-schema information and stores it in TBLPROPERTIES,
under {{avro.schema.literal}}.
> We'll need similar support in {{HCatLoader}} to prevent excessive reads of schema-files
in Pig queries.
