> User-provided hashes for operators
> ----------------------------------
>
> Key: FLINK-5480
> URL: https://issues.apache.org/jira/browse/FLINK-5480
> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Affects Versions: 1.2.0
> Reporter: Stefan Richter
> Assignee: Stefan Richter
>
> We could allow users to provided (alternative) hashes for operators in a
> StreamGraph. This can make migration between Flink versions easier, in case
> the automatically produced hashes between versions are incompatible. For
> example, users could just copy the old hashes from the web ui to their job.
