I hacked some code together locally and this does work. The question is how to 
do it in the correct manner.

> Spark has an {{OutputMetrics}} it uses to expose records / bytes written. We 
> currently don't integrate with it and the Spark UI shows a blank value for 
> output records / bytes. We have our own customer accumulators instead (like 
> Spark exposes the {{OutputMetrics}} object inside individual tasks via the 
> {{TaskContext.get()}} method. We can use this method to access the 
> {{OutputMetrics}} object and update it.
