> Spark Connect: Race condition in Streaming Query Listener Removal
> -----------------------------------------------------------------
>
> Key: SPARK-59623
> URL: https://issues.apache.org/jira/browse/SPARK-59623
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 4.0.4
> Reporter: Zifei Feng
> Priority: Major
> Labels: pull-request-available
>
> Previously, {{StreamingQueryListenerBus.remove}} called
> {{self._execution_thread.join()}} while holding {{{}self._lock{}}}. If the
> event thread had already received an event and was entering
> {{{}post_to_all{}}}, it needed the same lock to dispatch that event before it
> could terminate. The remover waited for the event thread, while the event
> thread waited for the remover's lock, causing a deadlock
