             Summary: Parquet filter pushdown does not support the native hive 
                 Key: DRILL-6331
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Hive
    Affects Versions: 1.13.0
            Reporter: Arina Ielchiieva
            Assignee: Arina Ielchiieva
             Fix For: 1.14.0

Initially HiveDrillNativeParquetGroupScan was based mainly on HiveScan, the 
core difference between them was
that HiveDrillNativeParquetScanBatchCreator was creating ParquetRecordReader 
instead of HiveReader.
This allowed to read Hive parquet files using Drill native parquet reader but 
did not expose Hive data to Drill optimizations.
For example, filter push down, limit push down, count to direct scan 
Hive code had to be refactored to use the same interfaces as ParquestGroupScan 
in order to be exposed to such optimizations.
