             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.
