[jira] [Created] (SPARK-33716) Decommissioning Race Condition during Pod Snapshot

Holden Karau created SPARK-33716:
------------------------------------

             Summary: Decommissioning Race Condition during Pod Snapshot
                 Key: SPARK-33716
                 URL: https://issues.apache.org/jira/browse/SPARK-33716
             Project: Spark
          Issue Type: Improvement
          Components: Kubernetes
    Affects Versions: 3.1.0, 3.2.0
            Reporter: Holden Karau
            Assignee: Holden Karau


Some version of Kubernetes may create a deletion timestamp field before changing the pod status to terminating, so a decommissioning node may have a deletion timestamp and a stage of running. Depending on when the K8s snapshot comes back this can cause a race condition with Spark believing the pod has been deleted before it has been.
