> Key: FLINK-4603
> URL: https://issues.apache.org/jira/browse/FLINK-4603
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0
> Reporter: Till Rohrmann
> Assignee: Stefan Richter
> Priority: Blocker
> Fix For: 1.2.0
>
>
> A user reported that he cannot restore keyed state which contains user code
> classes. I suspect that we don't use the user code class loader to
> deserialize the state.
> The solution seems to be to forward the user code class loader to the
> {{KeyedStateBackends}} when restoring state.
