             Summary: Report KafkaReceiver MessageHandler errors so StreamingListeners can take action
                 Key: SPARK-7621
                 URL: https://issues.apache.org/jira/browse/SPARK-7621
             Project: Spark
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 1.3.1
            Reporter: Jeremy A. Lucas


Currently, when a MessageHandler (for any of the Kafka Receiver implementations) encounters an error handling a message, the error is only logged with:

{code:none}
case e: Exception => logError("Error handling message", e)
{code}

It would be _incredibly_ useful to be able to notify any registered StreamingListener of this receiver error (especially since this {{try...catch}} block masks more fatal Kafka connection exceptions).
