[jira] Created: (MAPREDUCE-750) Extensible ConnManager factory API

Extensible ConnManager factory API
----------------------------------

                 Key: MAPREDUCE-750
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-750
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/sqoop
            Reporter: Aaron Kimball
            Assignee: Aaron Kimball


Sqoop uses the ConnFactory class to instantiate a ConnManager implementation based on the connect string and other arguments supplied by the user. This allows per-database logic to be encapsulated in different ConnManager instances, and dynamically chosen based on which database the user is actually importing from. But adding new ConnManager implementations requires modifying the source of a common ConnFactory class. An indirection layer should be used to delegate instantiation to a number of factory implementations which can be specified in the static configuration or at runtime.
