> This was added in SPARK-11314, but it has a few issues:
> - it's in the YARN module, which is not a public Spark API.
> - because of that it's also YARN specific
> - it's not used by Spark in any way other than providing this as an extension point
> For the latter, it probably makes sense to use listeners instead, and enhance the listener interface if it's lacking.
> Also pinging [~steve_l] since he added that code.
