When you use Oozie Coordinators to schedule activities, you specify a start and end date. If the start date is in the past, it will used that the date as the beginning and loop through the defined frequency until it reaches the current date. Each loop will launch with a "nominal" date. By default the loop will trigger every 5 minutes. If you're trying to catch up, this interval may be too slow for your needs.
Use the following Oozie configuration to adjust this triggering interval.
