Subject [jira] [Updated] (YARN-5326) Add support for recurring reservations in the YARN ReservationSystem
Date Thu, 07 Jul 2016 01:44:10 GMT

     [ https://issues.apache.org/jira/browse/YARN-5326?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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 ReservationSytem that enables the YARN
