Yufei Gu updated YARN-8059:
---------------------------
Description:
Method Fairscheduler#shouldAttemptPreemption doesn't consider resources other
than vcore and memory. We may need to rethink it in the resource type scenario.
{code}
if (context.isPreemptionEnabled()) {
return (context.getPreemptionUtilizationThreshold() < Math.max(
(float) rootMetrics.getAllocatedMB() /
getClusterResource().getMemorySize(),
(float) rootMetrics.getAllocatedVirtualCores() /
getClusterResource().getVirtualCores()));
}
{code}
