[jira] [Commented] (SQOOP-659) Design metadata upgrade procedure

["Hari Shreedharan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SQOOP-659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13603809#comment-13603809 ] 

Hari Shreedharan commented on SQOOP-659:
----------------------------------------

I am thinking of taking a stab at this. I think we need to modify the connector interface to add this method:

{code}
public List<PropertyDetails> upgrade(List<PropertyDetails>);

class PropertyDetails<T> {
  Class<?> propertyType; //for Type safety, so we can safely cast.
  String propertyName;
  Object propertyValue;
}

{code}

Does this make sense?
