[jira] [Created] (ORC-568) Make the convert tool sort the old _col column names by number

Owen O'Malley created ORC-568:
---------------------------------

             Summary: Make the convert tool sort the old _col<number> column names by number
                 Key: ORC-568
                 URL: https://issues.apache.org/jira/browse/ORC-568
             Project: ORC
          Issue Type: Improvement
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently the convert tool breaks on old orc files because the schema discovery tries to sort the fields and sorts as strings (eg. _col10 before _col9).
