---------------------------------
> Broken backward compatibility in PySpark: StreamingQueryListener due to the
> addition of onQueryIdle
> ---------------------------------------------------------------------------------------------------
>
> Key: SPARK-45631
> URL: https://issues.apache.org/jira/browse/SPARK-45631
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.5.0, 4.0.0
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 3.5.1, 4.0.0
>
>
> 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.
