> I tried setting spark.scheduler.mode=fair and I got the following nasty
> exception:
> {code}
> java.util.NoSuchElementException: None.get
> at scala.None$.get(Option.scala:313)
> at scala.None$.get(Option.scala:311)

> We should do two improvements:
> 1. We should make the built in ones case insensitive (fair/FAIR, fifo/FIFO).
> 2. If an invalid mode is given we should print a better error message.
