> Issue Type: Improvement
> Components: Connectors / Kafka
> Affects Versions: 1.11.0
> Reporter: jackylau
> Priority: Major
> Fix For: 1.12.0
>
>
> Flink master supports 0.10/0.11/2.x, with three flink-sql-connector shade jar
> currently (1.12-snapshot).
> As we all know ,kafka client is compatible after 0.10.2.x, so we can use
> kafka client 2.x to access to brocker server are 0.10/0.11/2.x.
> So we can just use one kafka sql shade jar.
> for this , we should do 2 things
> 1) refactor to 1 shade jar
> 2) rename flink-kafka-connector mudules with same qualified name in case of
> conflicts such as NoSuchMethod or ClassNotFound error
