> 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.
