             Summary: Add column level encryption to ORC files
                 Key: HIVE-4227
                 URL: https://issues.apache.org/jira/browse/HIVE-4227
             Project: Hive
          Issue Type: New Feature
            Reporter: Owen O'Malley


It would be useful to support column level encryption in ORC files. Since each 
column and its associated index is stored separately, encrypting a column 
separately isn't difficult. In terms of key distribution, it would make sense 
to use an external server like the one in HADOOP-9331.
