> In current Spark we could add customized {{SparkListener}} through {{SparkContext#addListener}} API, but there's no API to remove the registered one. In our scenario SparkListener will be added repeatedly accordingly to the changed environment. If lacks the ability to remove listeners, there might be bunch of registered listeners finally, this is unnecessary and potentially affect the performance. So here propose to add an API to remove registered listener.
