             Summary: Use uuid as app id in kubernetes client mode
                 Key: SPARK-36014
                 URL: https://issues.apache.org/jira/browse/SPARK-36014
             Project: Spark
          Issue Type: Bug
          Components: Kubernetes
    Affects Versions: 3.2.0
            Reporter: XiDuo You



Currently, spark on kubernetes with client mode would use `"spark-application-" + System.currentTimeMillis` as app id by default. It would cause app id conflict if submit several spark applications to kubernetes cluster in a short time.

Unfortunately, the event log use app id as the file name. With the conflict app id, the exception was thrown.
