             Summary: Support backing off dynamic allocation increases if resources are "stuck"
                 Key: SPARK-36060
                 URL: https://issues.apache.org/jira/browse/SPARK-36060
             Project: Spark
          Issue Type: Sub-task
          Components: Kubernetes
    Affects Versions: 3.2.0
            Reporter: Holden Karau


In a over-subscribed environment we may enter a situation where our requests for more pods are not going to be fulfilled. Adding more requests for more pods is not going to help and may slow down the scheduler. We should detect this situation and hold off on increasing pod requests until the scheduler allocates more pods to us. We have a limited version of this in the Kube scheduler it's self but it would be better to plumb this all the way through to the DA logic.
