> ---------------------------------------------------
>
> Key: SPARK-47899
> URL: https://issues.apache.org/jira/browse/SPARK-47899
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler, Spark Core
> Affects Versions: 3.4.0
> Reporter: Arjun Sahoo
> Assignee: BingKun Pan
> Priority: Minor
>
> As part of SPARK-39195, task is marked as failed but the exception chain was
> not sent, ultimately the cause becomes `null` in SparkException. It is not
> convenient to find the root cause from the detailed message.

> duplication may happen.
> */
> private[scheduler] def stageFailed(stageId: Int, reason: String): Unit = {
> eventProcessLoop.post(StageFailed(stageId, reason, None))
