Description

Currently there are a handful of ways in which queues are able to access node labels. A non-exhaustive list of these are:

1. configuredNodeLabels
2. getNodeLabelsForQueue()
3. QueueCapacities#getNodePartitionsSet()
4. ResourceUsage#getNodePartitionsSet()
5. accessibleNodeLabels

It is worth revisiting, as there already is a bug, which was implicitly caused by this inconsistency (YARN-11016).
