Maximilian Michels commented on FLINK-3273:
-------------------------------------------
The idea was to have a Scala-free version of {{flink-streaming-java}},
currently we have {{flink-streaming-java_2.11}} and
{{flink-streaming-java_2.12}}. We would require a runtime-decoupled
abstraction, similar to what {{flink-java}} has but for streaming. Then we
could get rid of the Scala dependency.
Not sure if there are plans at the moment to do that because it would be an
invasive change.

> Reporter: Maximilian Michels
> Priority: Major

> {{flink-streaming-java}} depends on Scala through {{flink-clients}},
> {{flink-runtime}}, and {{flink-testing-utils}}. We should get rid of the
> Scala dependency just like we did for {{flink-java}}. Integration tests and
> utilities which depend on Scala should be moved to {{flink-tests}}.
