Github user MaxGekk commented on the issue: https://github.com/apache/spark/pull/22429 As far as I know, @hvanhovell, you would prefer replacing `Option[Int]` by just `Int` in `simpleString` and other similar places. I can do that but I have to read the config parameter in all those places where I pass `None` at the moment. I have counted ~ 26 places. @zsxwing Do you also prefer this approach?
