> Project: Flink
> Issue Type: Improvement
> Reporter: Fabian Hueske
> Assignee: Fabian Hueske
> Priority: Major
> Labels: pull-request-available
>
> I recently noticed that we do not guarantee client-jobmanager compatibility
> among different bugfix versions of the same minor version (see
> https://github.com/ververica/sql-training/issues/8 for details).
> In this case, a job submitted via a Flink 1.9.0 client could not be executed
> on a Flink 1.9.2 cluster.
> For the playgrounds this can easily happen, because we build a custom Docker
> image (with a fixed bugfix version) and load the latest Flink images for the
> latest bugfix version of the same minor version.
> We can avoid such problems by fixing the bugfix version of the Flink images
> that we run in the playground.
