> 2 enhancements:
> 1. Check that retention should not be more frequent than the data availability.
> 2. Oozie doesn't behave appropriately for retention for high frequencies like minutes(3)
etc. Retention follows LAST_ONLY execution order and for high frequencies and default configuration
retention might not execute. To make it work you will need to override 
> oozie.service.CoordMaterializeTriggerService.materialization.window
> and
> oozie.service.CoordMaterializeTriggerService.lookup.interval
> which might affect the Oozie system performance.
> Hence we should set a limit like hours(1) for retention frequency and retention more
frequent than that should throw validation error.
