             Summary: Sqoop2: "Migration style" upgrades for connectors and 
drivers
                 Key: SQOOP-2616
                 URL: https://issues.apache.org/jira/browse/SQOOP-2616
             Project: Sqoop
          Issue Type: Improvement
            Reporter: Abraham Fine


With SQOOP-1732 we now are able to specify the version we are coming from for 
connector developers to supply upgraders. In the case where a user skips a 
version in the upgrade, say from version A to version C (skipping version B) a 
connector developer would need to, at one point or another, write the following 
upgraders.

A -> B
B -> C
A -> C

Our upgrading logic should allow connector developers to only need to write:
A -> B
B -> C

and call them sequentially during a single upgrade procedure.
