> ------------------------------------------------------------------------------------------

> Key: SPARK-34245
> URL: https://issues.apache.org/jira/browse/SPARK-34245
> Project: Spark
> Issue Type: Improvement
> Components: Deploy, Spark Core
> Affects Versions: 2.4.7, 3.0.1, 3.2.0, 3.1.1
> Reporter: wuyi
> Assignee: wuyi
> Priority: Major
>
> If the Worker fails to send ExecutorStateChanged to the Master due to some
> errors, e.g., temporary network error, then the Master can't remove the
> finished executor normally and think the executor is still alive. In the
> worst case, if the executor is the only one executor for the application, the
> application can get hang.
