---------------------------------
Summary: 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
Reporter: Josh Rosen
Assignee: Josh Rosen
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.
