Gyula Fora created FLINK-4441:
---------------------------------
Summary: RocksDB statebackend makes all operators appear stateful
Key: FLINK-4441
URL: https://issues.apache.org/jira/browse/FLINK-4441
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing, Streaming
Affects Versions: 1.1.1
Reporter: Gyula Fora
Assignee: Gyula Fora
Priority: Blocker
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.
