Description

In current hive upstream 2.1version, when hive tried to insert empty list or empty map to parquet table, it fails with error:
parquet.io.ParquetEncodingException: empty fields are illegal, the field should be ommited completely instead

It seems now parquet only support null value, we should find a way to support empty list and empty map values.
