[jira] [Created] (HIVE-5998) Add vectorized reader for Parquet files

Remus Rusanu created HIVE-5998:
----------------------------------

             Summary: Add vectorized reader for Parquet files
                 Key: HIVE-5998
                 URL: https://issues.apache.org/jira/browse/HIVE-5998
             Project: Hive
          Issue Type: Sub-task
            Reporter: Remus Rusanu
            Assignee: Remus Rusanu
            Priority: Minor


HIVE-5783 is adding native Parquet support in Hive. As Parquet is a columnar format, it makes sense to provide a vectorized reader, similar to how RC and ORC formats have, to benefit from vectorized execution engine.
