      Description

      Parquet's Avro and Thrift object models don't produce the same parquet type representation for lists and maps that Hive does. In the Parquet community, we've defined what should be written and backward-compatibility rules for existing data written by parquet-avro and parquet-thrift in PARQUET-113. We need to implement those rules in the Hive Converter classes.
