Pleas echeck your Oozie Sharedlib if you have placed the mysql-connector-java jar inside it?
# oozie admin -oozie http://$OOZIE_HOST:11000/oozie -shareliblist
Also please check if you have imported the Mysql connector jDBC driver inside the "/user/oozie/share/lib/*/sqoop" and have run the "sharelibupdate" command?
# oozie admin -oozie http://$HOSTNAME:11000/oozie -sharelibupdate
