> Parquet filter pushdown does not support the native hive reader
> ---------------------------------------------------------------
>
> Key: DRILL-6331
> URL: https://issues.apache.org/jira/browse/DRILL-6331
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Hive
> Affects Versions: 1.13.0
> Reporter: Arina Ielchiieva
> Assignee: Arina Ielchiieva
> Priority: Major
> 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
> optimizations.
> Hive code had to be refactored to use the same interfaces as
> ParquestGroupScan in order to be exposed to such optimizations.
