Description

There are incompatibilities in the way that some parquet object models translate nested structures annotated by LIST and MAP / MAP_KEY_VALUE. We need to define clearly what the structures should look like and how to interpret existing structures, including what must be supported to read current parquet-avro, parquet-thrift, etc. files.
