> Key: HIVE-25362
> URL: https://issues.apache.org/jira/browse/HIVE-25362
> Project: Hive
> Issue Type: Sub-task
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Major
>
> 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 being added to the DelayQueue leading to
> worse locality when all LLap resources are fully utilized.
> To address the issue we should handle the two cases separately.
