Hi [~jerluc], you could submit a related PR on Github, Spark community submits patch on Github rather than JIRA.

> 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).
