Hi, Is there any plan to add the countByValue function to Spark SQL Dataframe ? Even https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/feature/StringIndexer.scala#L78 is using the RDD part right now, but for ML purposes, being able to get the most frequent categorical value on multiple columns would be very useful.
