> Start faulthandler early in daemon mode
> ---------------------------------------

> Key: SPARK-54740
> URL: https://issues.apache.org/jira/browse/SPARK-54740
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Tian Gao
> Priority: Major
> Labels: pull-request-available
>
> It's possible that our worker process has issues before the worker main
> function executes - but faulthandler is not attached so we can't really do
> anything about it. We hook faulthandler on the worker main function because
> that's the common path for daemon and simple mode. However, we can make the
> faulthandler helper reentry friendly so we can start it early in daemon mode
> without changing the simple mode code.
