      Description

      YARN-1051 introduced a ReservationSytem that enables the YARN RM to handle time explicitly, i.e. users can now "reserve" capacity ahead of time which is predictably allocated to them. Most SLA jobs/workflows are recurring so they need the same resources periodically. With the current implementation, users will have to make individual reservations for each run. This is an umbrella JIRA to enhance the reservation system by adding native support for recurring reservations.
