[jira] [Created] (HIVE-17697) Remove Parquet specific code from VectorizedColumnReader

Vihang Karajgaonkar created HIVE-17697:
------------------------------------------

             Summary: Remove Parquet specific code from VectorizedColumnReader
                 Key: HIVE-17697
                 URL: https://issues.apache.org/jira/browse/HIVE-17697
             Project: Hive
          Issue Type: Sub-task
            Reporter: Vihang Karajgaonkar


Lot of code in VectorizedColumnReader class deals with Parquet internal decoding logic which should ideally be available from Parquet library instead of duplicating it in Hive code. We should work with Parquet community to get public APIs for this code or implement  vectorization support  natively so that this code can be removed from Hive code base.
