> 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 {{HIVE_RECORDS_OUT}}).
> 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.
