> 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
> Fix For: 3.3.0
>
>
> 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.
