Aaron Kimball commented on MAPREDUCE-750:
-----------------------------------------
I should point out -- I'm all for not cluttering up the mapred-, hdfs- and
core-* config files with extraneous parameters. Is there a better place to put
this? Can/should we have a contrib-default and contrib-site? (Or, inevitably,
per-contrib-module config files?)

> 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.
