>             Project: Flink
>          Issue Type: Bug
>          Components: State Backends, Checkpointing, Streaming
>    Affects Versions: 1.1.1

> When the state is empty the rocks db state backend returns an empty hashmap instead of a null in the snapshotPartitionedState method.
> This means that these operators always appear stateful to the flink runtime which makes it impossible for instance to remove a stateless operator using the savepoints.
