cc @gszadovszky @shangxinli The problem is that DataSource v2 will push down the partition filter to [`SpecificParquetRecordReaderBase`](https://github.com/apache/spark/blob/26badc4cc4ea6d68c8c5d50cf2c83e4904aacc0d/sql/core/src/main/java/org/apache/spark/sql/execution/datasources/parquet/SpecificParquetRecordReaderBase.java#L138-L153) or [`InternalParquetRecordReader`](https://github.com/apache/parquet-mr/blob/86808425d5f67ddb2b4c80b1d1a06015bc92be10/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordReader.java#L185). If we use `reader.getFilteredRecordCount()`, the result is empty. Do you think it should be fixed on the Parquet side or Spark side? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
