------------------------------------------
Summary: ExecutorPodsAllocator fails to identify some excess
requests during downscaling
Key: SPARK-34334
URL: https://issues.apache.org/jira/browse/SPARK-34334
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 3.1.0, 3.2.0
Reporter: Attila Zsolt Piros
During downscaling there are two kinds of POD requests which can lead to POD
deletion as it is identified as excess requests by the dynamic allocation:
* timed out newly created POD requests (which even haven't reached the Pod
Pending state, yet)
* timed out pending pod requests
The current implementation fails to delete a timed out pending pod requests
when there are not enough timed out newly created POD requests to delete but
there are some non-timed out ones.
