>             Project: Spark
>          Issue Type: Bug
>          Components: Examples, Streaming
>    Affects Versions: 2.0.0
>            Reporter: Xin Ren
>            Priority: Minor
>
> `object StreamingExamples` is more of a utility object, and the name is too 
> general and I thought it's an actual streaming example at the very beginning.
