> I have code [here|http://stackoverflow.com/questions/49440766/trouble-getting-spark-aggregators-to-work] where I am trying to use an Aggregator with both the select and agg functions. I cannot seem to get this to work in Spark 2.3.0. [Here|https://docs.cloud.databricks.com/docs/spark/1.6/examples/Dataset%20Aggregator.html] is a blog post that appears to be using this functionality in Spark 1.6, but It appears to no longer work.
