---------------------------------------

             Summary: Deserialize StateBackend from JobCheckpointingSettings with user classloader
                 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: 1.3.1, 1.3.0
            Reporter: 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.
