-----------------------------------
Summary: Add an API to remove SparkListener from SparkContext
Key: SPARK-18975
URL: https://issues.apache.org/jira/browse/SPARK-18975
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Saisai Shao
Priority: Minor
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.
