             Summary: 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


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
