Ismael, the SDK should perform the pipeline translation to proto because I expect the flow to be: User Code -> SDK -> Proto Translation -> Job API -> Runner I don't expect "runners" to live within the users process anymore (excluding the direct runner). There will be one portable "runner" and it will be responsible for communicating with the job management APIs. It shouldn't be called a runner but for backwards compatibility it will behave like a runner does today. Flink/Spark/... will all live on the other side of the job management API.
Thomas, I can run RemoteExectuionTest from commit ae2bebaf8b277e99840fa63f1b95d828f2093d16 without needing to modify the project/module structure in Intellij. Adding the jars manually only helps with code completion. https://github.com/apache/beam/pull/5977 works around the duplicate content root issue in Intellij. I have also run into the -Werror issue occasionally and don't know any fix or why it gets triggered as it doesn't happen to me all the time.
