Stephan Ewen commented on FLINK-3154:
-------------------------------------
I would like to close this as "won't fix".
This can only be addressed as part of a bigger initiative to introduce
versioning for serializers, otherwise we break all savepoint compatibility.
> Update Kryo version from 2.24.0 to 3.0.3

> Key: FLINK-3154
> URL: https://issues.apache.org/jira/browse/FLINK-3154
> Project: Flink
> Issue Type: Improvement
> Components: Build System
> Affects Versions: 1.0.0
> Reporter: Maximilian Michels
> Priority: Minor
> Fix For: 1.0.0
>
>
> Flink's Kryo version is outdated and could be updated to a newer version,
> e.g. kryo-3.0.3.
> From ML: we cannot bumping the Kryo version easily - the serialization format
> changed (that's why they have a new major version), which would render all
> Flink savepoints and checkpoints incompatible.
