Hi, I think there is a issue that:
* if you want to no overwrite in a exist file, you will get the error "File
already exists"
* if you want to no overwrite and the file is not exist, the `NO_OVERWRITE`
is just the same as `OVERWRITE`
So I think currently the `NO_OVERWRITE` is not make sense.
Maybe we need discuss and fix on it through a new JIRA?
> Scala DataStream API does not have writeAsText method which supports WriteMode

> Key: FLINK-2622

> 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.
