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

             Summary: HeapKeyedStateBackend restorig broken for scale-in
                 Key: FLINK-4731
                 URL: https://issues.apache.org/jira/browse/FLINK-4731
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter
            Assignee: Stefan Richter


Restoring the HeapKeyedStateBackend is broken in case that parallelism is reduced. The restore method is overwriting previously restored state.

We should also add scale-in testing to the RescalingITCase.
