@StephanEwen Thanks Stephan. To your comments:
1. in order to have `experiemental/scala` package in
`flink-streaming-scala`, I have to make `DataStreamUtils` its own class to
avoid package name collisions with `scala`
2. I don't think checkstyle of the whole project`flink-streaming-scala` is
active. I did some tests which removed comments and left unused class imports,
the build still passed. I think we should address enabling checkstyle
separately, may need to reopen[FLINK-6902](

> Project: Flink
> Issue Type: Sub-task

> I propose removing flink-streaming-contrib from flink-contrib, and migrating
> its classes to flink-streaming-java/scala for the following reasons:
> - flink-streaming-contrib is so small that it only has 4 classes (3 java and
> 1 scala), and they don't need a dedicated jar for Flink to distribute and
> maintain it and for users to deal with the overhead of dependency management
> - the 4 classes in flink-streaming-contrib are logically more tied to
> flink-streaming-java/scala, and thus can be easily migrated
> - flink-contrib is already too crowded and noisy. It contains lots of sub
> modules with different purposes which confuse developers and users, and they
> lack a proper project hierarchy
> To take a step even forward, I would argue that even flink-contrib should be
> removed and all its submodules should be migrated to other top-level modules
> for the following reasons: 1) Apache Flink the whole project itself is a
> result of contributions from many developers, there's no reason to highlight
> some contributions in a dedicated module named 'contrib' 2) flink-contrib
> inherently doesn't have a good hierarchy to hold submodules
