> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.4.0
> Reporter: Josh Rosen

> Priority: Minor
> Fix For: 3.4.0
>
>
> If {{spark.scheduler.listenerbus.metrics.maxListenerClassesTimed}} has been
> set to {{0}} to disable listener timers then listener registration will
> trigger noisy warnings like
> {code:java}
> LiveListenerBusMetrics: Not measuring processing time for listener class
> org.apache.spark.sql.util.ExecutionListenerBus because a maximum of 0
> listener classes are already timed.{code}
> warnings.
> We should change the code to not print this warning when
> maxListenerClassesTimed = 0.
> I don't plan to work on this myself.
