> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: 4.0.0
> Reporter: Niranjan Jayakar

> We added new assertions to the AddArtifact RPC -
> [https://github.com/apache/spark/commit/d9c5f9d6#diff-d4744c7abd099c57d04746140aba3c20b93f1ac011f5915f963e0a3e0758690e]
> As part of this change, we have also updated the RPC implementation to return
> session id as part of its response.
>
> Since the assertion depends on the session id to be present, it makes the
> protocol incompatible such that newer Connect clients that apply this
> assertion are incompatible with older clusters that don't have the
> corresponding service side changes.
