> 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
> Priority: Major
>
> 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 event log file, the exception was thrown.
> {code:java}
> Caused by: java.io.FileNotFoundException: File does not exist: xxx/spark-application-1624766876324.lz4.inprogress (inode 5984170846) Holder does not have any open files.
