[jira] [Created] (FLINK-2399) Fail when actor versions don't match

[Shang Yuanchun (Jira)]

Ufuk Celebi created FLINK-2399:
----------------------------------

             Summary: Fail when actor versions don't match
                 Key: FLINK-2399
                 URL: https://issues.apache.org/jira/browse/FLINK-2399
             Project: Flink
          Issue Type: Improvement
          Components: JobManager, TaskManager
    Affects Versions: 0.9, master
            Reporter: Ufuk Celebi
            Priority: Minor
             Fix For: 0.10


Problem: there can be subtle errors when actors from different Flink versions communicate with each other, for example when an old client (e.g. Flink 0.9) communicates with a new JobManager (e.g. Flink 0.10-SNAPSHOT).

We can check that the versions match on first communication between the actors and fail if they don't match.
