[jira] [Created] (SPARK-45631) Broken backward compatibility in PySpark: StreamingQueryListener due to the addition of onQueryIdle

Jungtaek Lim created SPARK-45631:
------------------------------------

             Summary: 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


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.
