>                 Key: SPARK-42173
>                 URL: https://issues.apache.org/jira/browse/SPARK-42173
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 3.4.0
>         Environment: I've only observed this on Kube but it might be able to happen on YARN since the mapping is in core.
