------------------------------

             Summary: Resource type is ignored when FS decide to preempt
                 Key: YARN-8059
                 URL: https://issues.apache.org/jira/browse/YARN-8059
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 3.0.0
            Reporter: Yufei Gu


Method Fairscheduler#shouldAttemptPreemption doesn't consider resources other than vcore and memory. We may need to rethink it.
{code}
    if (context.isPreemptionEnabled()) {
      return (context.getPreemptionUtilizationThreshold() < Math.max(
          (float) rootMetrics.getAllocatedMB() /
              getClusterResource().getMemorySize(),
          (float) rootMetrics.getAllocatedVirtualCores() /
              getClusterResource().getVirtualCores()));
    }
{code}
