Github user uce commented on the issue: https://github.com/apache/flink/pull/3387 If I understand this correctly, this gets rid of duplicated code. I think this is in general very valuable, but the problem is queryable state right now is that we need to refactor this for 1.3 anyways. Currently, too many `flink-runtime` components are exposed to the user. I'm working on a FLIP to improve the user APIs for 1.3 and deprecated (or maybe even remove) the current APIs. This will therefore become obsolete. What do you think? Should we close this PR and issue and you help on the proposed changes instead?
