I have a spark data frame df. Is there a way of sub selecting a few columns using a list of these columns?
res0: Array[String] = Array("a", "b", "c", "d")
I know I can do something like df.select("b", "c"). But suppose I have a list containing a few column names val cols = List("b", "c"), is there a way to pass this to df.select? df.select(cols) throws an error. Something like df.select(*cols) as in python
