Subject [jira] [Created] (YARN-3691) Limit number of reservations for an app
Date Wed, 20 May 2015 17:32:00 GMT
Arun Suresh created YARN-3691:
---------------------------------

             Summary: Limit number of reservations for an app
                 Key: YARN-3691
                 URL: https://issues.apache.org/jira/browse/YARN-3691
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
            Reporter: Arun Suresh


Currently, It is possible to reserve resource for an app on all nodes. Limiting this to possibly
just a number of nodes (or a ratio of the total cluster size) would improve utilization of
the cluster and will reduce the possibility of starving other apps.
