------------------------------------
Actually this doesn't look like something we need for 1.2.x, does it?
> Add SparkListener implementation that allows users to receive all listener
> events in one method

> Key: SPARK-5414
> URL: https://issues.apache.org/jira/browse/SPARK-5414
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Fix For: 1.3.0
>
>
> Currently, users don't have a very good way to write a SparkListener that
> receives all SparkListener events and which will be future-compatible (e.g.
> it will receive events introduced in newer versions of Spark without having
> to override new methods to process those events).
> Therefore, I think Spark should include a concrete SparkListener
> implementation that implements all of the message-handling methods and
> dispatches all of them to a single {{onEvent}} method. By putting this code
> in Spark, we isolate users from changes to the listener API.
