Issue Type: Improvement (was: Sub-task)
Parent: (was: YARN-2572)
> Supporting "priorities" in the ReservationSystem
> ------------------------------------------------

> Key: YARN-5211
> URL: https://issues.apache.org/jira/browse/YARN-5211
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacityscheduler, fairscheduler, resourcemanager
> Reporter: Carlo Curino
> Assignee: Sean Po
>
> 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.
