------------------------------------
Summary: KeyedStateBackend cannot restore user code classes
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
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.
