Daniel Weeks created HIVE-6938:
----------------------------------

             Summary: Add Support for Parquet Column Rename
                 Key: HIVE-6938
                 URL: https://issues.apache.org/jira/browse/HIVE-6938
             Project: Hive
          Issue Type: Improvement
          Components: File Formats
    Affects Versions: 0.13.0
            Reporter: Daniel Weeks


Parquet was originally introduced without 'replace columns' support in ql.  In addition, the default behavior for parquet is to access columns by name as opposed to by index by the Serde.  

Parquet should allow for either columnar (index based) access or name based access because it can support either.
