---------------------------------------------
Summary: LLAP: ensure tasks with locality are added to DelayQueue
Key: HIVE-25362
URL: https://issues.apache.org/jira/browse/HIVE-25362
Project: Hive
Issue Type: Bug
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
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.
