             Summary: Intra-queue preemption: apps that don't use defined custom resource won't be preempted.
                 Key: YARN-10834
                 URL: https://issues.apache.org/jira/browse/YARN-10834
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Eric Payne
            Assignee: Eric Payne


YARN-8292 added handling of negative resources during the preemption calculation phase. That JIRA hard-coded it so that for inter-(cross-)queue preemption, the a single resource in the vector could go negative while calculating ideal assignments and preemptions. It also hard-coded it so that during intra-(in-)queue preemption calculations, no resource could not go negative. YARN-10613 made these options configurable.

However, in clusters where custom resources are defined, apps that don't use the extended resource won't be preempted.
