> 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.
