> Key: FLINK-7041
> URL: https://issues.apache.org/jira/browse/FLINK-7041
> Project: Flink
> Issue Type: Bug
> Components: DataStream API, Distributed Coordination, State Backends, Checkpointing
> Affects Versions: 1.3.0, 1.3.1
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Blocker
> Fix For: 1.3.2
>
>
> A user ran into the problem that the {{SubmitJob}} message is not (de)serialisable if it contains custom RocksDB options (or a custom state backend): [1]
> The problem is that {{SubmitJob}} contains a {{JobGraph}} which contains {{JobCheckpointingSettings}} which contains a {{StateBackend}}. This {{StateBackend}} potentially has user code and therefore can only be deserialised with the user classloader.
> This issue is mostly identical to FLINK-6531.
