> HIVE-24914 introduced a short-circuit optimization when all nodes are busy
> returning DELAYED_RESOURCES and reseting locality delay for a given tasks.
> However, this may prevent tasks from adjusting their locality delay and being
> added to the DelayQueue leading sometimes to missed locality chances when all
> LLap resources are fully utilized.
> To address the issue we should handle the two cases separately.
