             Summary: Supporting "priorities" in the ReservationSystem
                 Key: YARN-5211
                 URL: https://issues.apache.org/jira/browse/YARN-5211
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Carlo Curino
            Assignee: Carlo Curino


The ReservationSystem currently has an implicit FIFO priority. This JIRA tracks effort to
generalize this to arbitrary priority. This is non-trivial as the greedy nature of our ReservationAgents
might need to be revisited if not enough space if found for late-arriving but higher priority
reservations.
