customerDF.groupBy("state").agg(max($"discount").alias("newName"))
(or .as(...), both functions can take a String or a Symbol)

I would like to ask if there is a way of specifying the column name of a
data frame aggregation. For example If I do:
customerDF.groupBy("state").agg(max($"discount"))
the name of my aggregated column will be: MAX('discount)
Is there a way of changing the name of that column to something else on
