Subru Krishnan updated YARN-5326:
---------------------------------
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. (was: YARN-1051 introduced a
