     [ https://issues.apache.org/jira/browse/FLINK-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

    Fix Version/s:     (was: 1.0.0)

> 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: Distributed Coordination, JobManager
>    Affects Versions: 0.9, 0.10.0

>            Priority: Minor

> 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.
