> YARN-1769 brought in reservations continue looking feature which improves the
> several resource reservation scenarios. However, it is not handled currently
> when nodes have a label assigned to them. This is useful and in many cases
> necessary even for Node Labels. So we should look to support this for node
> labels also.
> For example, in AbstractCSQueue.java, we have the below TODO.
> {code:java}
> // TODO, now only consider reservation cases when the node has no label
> if (this.reservationsContinueLooking && nodePartition.equals(
> RMNodeLabelsManager.NO_LABEL) && Resources.greaterThan( resourceCalculator,
> clusterResource, resourceCouldBeUnreserved, Resources.none())) {
> {code}
