描述

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.

调研方向

首先检查 ParquetReader 的 Hadoop 专用方法,以及与 PARQUET-2381 和 issue 2838 相关的讨论。创建此处描述的专用 HadoopParquetReader,同时考虑迁移文档和未来的 deprecation 路径;当新类提供预期的、脱离与 Hadoop 耦合的 ParquetReader 方法的过渡时,即视为完成。
