             Summary: Handle BroadcastState with finished operators
                 Key: FLINK-23475
                 URL: https://issues.apache.org/jira/browse/FLINK-23475
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
            Reporter: Dawid Wysakowicz


BroadcastState assumes all subtasks state is the same. When rescaling it 
reassigns states of all tasks to new tasks. If the parallelism is different it 
assigns the old states to new range of states in a round robin fashion.

We must make sure that an empty state is not reassigned to running subtasks in
