We already have test for the pushed down filters for ParquetRecordReader.
But it is at individual record level. If you mean row group level, because
ParquetRecordReader doesn't expose a count for the row group, I think we can't
check if the filter is pushed down. Besides, it seems to be the functionality
of ParquetRecordReader, and I think it should be unit test in parquet project.
