             Summary: DaemonSet preemption: don't flood the logs if victim selection fails
                 Key: YUNIKORN-2980
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-2980
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - scheduler
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


If we can't find a proper victim for a DaemonSet pod, we constaly print the following to the console in every scheduling cycle:

{noformat}
log.Log(log.SchedApplication).Info("Triggering preemption process for daemon set ask",
		zap.String("ds allocation key", ask.GetAllocationKey()))
[...]
log.Log(log.SchedApplication).Warn("Problem in finding the victims for preempting resources to meet required ask requirements",
		zap.String("ds allocation key", ask.GetAllocationKey()),
		zap.String("node id", reserve.nodeID))
{noformat}

Since we attempt to schedule in every 100ms, this is logged at least 10 times in every second.

Suggestion: do the preemption silently and only log if it has succeeded, just like regular preemption. Otherwise, use {{Allocation.LogAllocationFailure()}} which we already do for a variety of things.
