> SparkListener.onOtherEvent was added in
> https://github.com/apache/spark/pull/10061. SQLListener uses it to dispatch
> SQL special events instead of creating a new separate listener bus.
> Streaming can also use the similar approach to eliminate the
> StreamingListenerBus. Right now, nondeterministic message order in two
> listener buses are really tricky when someone implements both SparkListener
> and StreamingListener. And if we can use only one listener bus in Spark, the
> nondeterministic message order will be eliminated and we can also remove a
> lot of codes.
