Subject [jira] [Created] (YARN-3632) Ordering policy should be allowed to reorder an application when demand changes
Date Tue, 12 May 2015 13:38:00 GMT
Craig Welch created YARN-3632:
---------------------------------

             Summary: Ordering policy should be allowed to reorder an application when demand
changes
                 Key: YARN-3632
                 URL: https://issues.apache.org/jira/browse/YARN-3632
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Craig Welch
            Assignee: Craig Welch


At present, ordering policies have the option to have an application re-ordered (for allocation
and preemption) when it is allocated to or a container is recovered from the application.
 Some ordering policies may also need to reorder when demand changes if that is part of the
ordering comparison, this needs to be made available (and used by the fairorderingpolicy when
sizebasedweight is true)
