[jira] [Created] (YARN-2475) ReservationSystem: replan upon capacity reduction

Carlo Curino created YARN-2475:
----------------------------------

             Summary: ReservationSystem: replan upon capacity reduction
                 Key: YARN-2475
                 URL: https://issues.apache.org/jira/browse/YARN-2475
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: Carlo Curino
            Assignee: Carlo Curino


In the context of YARN-1051, if capacity of the cluster drops significantly upon machine failures we need to trigger a reorganization of the planned reservations. As reservations are "absolute" it is possible that they will not all fit, and some need to be rejected a-posteriori.
