> Hive use deprecated ParquetInputSplit in [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/io/parquet/ParquetRecordReaderBase.java#L128]
> Please see interface definition in [https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetInputSplit.java#L80]
> Old interface set rowgroupoffset values which will lead to skip dictionary filter in
parquet.
