> NPE in FifoCandidatesSelector.selectCandidates when preempting resources for

> Key: YARN-11801
> URL: https://issues.apache.org/jira/browse/YARN-11801
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn
> Affects Versions: 3.4.0, 3.5.0
> Reporter: Susheel Gupta
> Assignee: Susheel Gupta
> Priority: Major
> Labels: pull-request-available
>
> When enabling the ProportionalCapacityPreemptionPolicy in the YARN
> SchedulingMonitor, I encountered a NullPointerException in
> {{{}FifoCandidatesSelector.selectCandidates{}}}. This happens when an
> auto-created queue exists but does not have any child queues.
> A childless ParentQueue will throw a NPE in
> FifoCandidatesSelector#selectCandidates:
> {code:java}
> LeafQueue leafQueue = preemptionContext.getQueueByPartition(queueName,
> RMNodeLabelsManager.NO_LABEL).leafQueue;{code}
> NullPointer stack trace:
> {code:java}
> 2025-03-24 08:36:12,593 ERROR monitor.SchedulingMonitor: Exception raised
