Subject [jira] [Created] (YARN-6227) Information about reservations that are yielded by higher priority reservations need to be surfaced to the client
Date Thu, 23 Feb 2017 21:49:44 GMT
Sean Po created YARN-6227:
-----------------------------

             Summary: Information about reservations that are yielded by higher priority reservations
need to be surfaced to the client
                 Key: YARN-6227
                 URL: https://issues.apache.org/jira/browse/YARN-6227
             Project: Hadoop YARN
          Issue Type: Task
            Reporter: Sean Po


YARN-5385 introduces a PriorityReservationAgent that can be used to yield lower priority reservations
so that higher priority reservations may fit if it initially could not be created in the plan.
In the event that a low priority reservation is yielded, the client does not have a way to
know prior to using the reservation that it has been removed. This JIRA aims to surface such
information to the client, so that it may be able to act appropriately to its lost reservation.
