> Recover job state at the granularity of operator

> Key: FLINK-5892
> URL: https://issues.apache.org/jira/browse/FLINK-5892
> Project: Flink
> Issue Type: New Feature
> Components: State Backends, Checkpointing
> Reporter: Guowei Ma
> Assignee: Guowei Ma
>
> JobGraph has no `Operator` info so `ExecutionGraph` can only recovery at the
> granularity of task.
> This leads to the result that the operator of the job may not recover the
> state from a save point even if the save point has the state of operator.
