The semantics of `NO_OVERWRITE` are correct and pretty clear, IMO.
If we would change `NO_OVERWRITE` to even fail if there is no file, it's
semantics would change to `NO_WRITE` and always fail.

> Project: Flink
> Issue Type: Bug
> Components: Scala API, Streaming
> Reporter: Till Rohrmann
>
> The Scala DataStream API, unlike the Java DataStream API, does not support a
> {{writeAsText}} method which takes the {{WriteMode}} as a parameter. In order
> to make the two APIs consistent, it should be added to the Scala DataStream
> API.
