Create specialized HadoopParquetReader

Setting up a specialized HadoopParquetReader allows for deprecating the Hadoop specific methods in ParquetReader as in PARQUET-2381. This could allow for an easier and more gentle transition away from the current Hadoop-coupled Parquet reader API by encouraging transitioning to this specialized class already, before completely phasing out the Hadoop methods from ParquetReader in the future.

まず、ParquetReader の Hadoop 固有のメソッドと、関連する PARQUET-2381 および issue 2838 の議論を確認してください。ここで説明されている専用の HadoopParquetReader を作成し、移行ドキュメントと将来の deprecation パスを念頭に置いてください。新しいクラスが、Hadoop に結合された ParquetReader のメソッドから意図された移行を提供すれば完了です。
