Subject [jira] [Created] (ORC-120) Create a backwards compatibility mode of ignoring names for evolution
Date Mon, 12 Dec 2016 22:24:58 GMT
Owen O'Malley created ORC-120:
---------------------------------

             Summary: Create a backwards compatibility mode of ignoring names for evolution
                 Key: ORC-120
                 URL: https://issues.apache.org/jira/browse/ORC-120
             Project: Orc
          Issue Type: Task
            Reporter: Owen O'Malley


ORC's schema evolution uses the column names when they are available. Hive 2.1 uses a positional
schema, so ORC should support a backward compatibility mode for Hive users during the transition.
