> We observed the issue that existing StreamingQueryListener implementations in PySpark start to fail after upgrading to 3.5.0. We identified that the root cause is https://issues.apache.org/jira/browse/SPARK-43183 since onQueryIdle was defined as `@abstractmethod`, requiring all exiting implementations to implement the method.
> It seems like abstractmethod annotation should be removed to retain backward compatibility.
