Yufei Gu created YARN-8059:
------------------------------
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}
