[jira] [Created] (SPARK-14358) Change SparkListener from a trait to an abstract class, and remove JavaSparkListener

Reynold Xin created SPARK-14358:
-----------------------------------

             Summary: Change SparkListener from a trait to an abstract class, and remove JavaSparkListener
                 Key: SPARK-14358
                 URL: https://issues.apache.org/jira/browse/SPARK-14358
             Project: Spark
          Issue Type: Sub-task
          Components: Scheduler, Spark Core
            Reporter: Reynold Xin
            Assignee: Reynold Xin


Scala traits are difficult to maintain binary compatibility on, and as a result we had to introduce JavaSparkListener. In Spark 2.0 we can change SparkListener from a trait to an abstract class and then remove JavaSparkListener.
