Hi Frank, If you use the Java action, you should be able to do just about anything you want in there. So, if you wanted to write your own driver class, you can use the Java action to have Oozie run it, and do all configuration for your MR job from within your driver class; if I recall correctly, you can set the number of reducers from the JobConf object (in your driver).
