MaGuowei updated FLINK-5892:
----------------------------
Description:
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.
