Description

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

Research direction

Start by reading the existing ParquetWriter API and the related PARQUET-2381 and issue 2838 discussions, then review the migration documentation referenced in PARQUET-2502. Define the scope of HadoopParquetWriter and confirm how it supports the planned deprecation of Hadoop-specific ParquetWriter methods. Done means the specialized class and transition path are clearly established.
