[jira] [Created] (FLINK-21084) Allows tasks to report operator subtask finish state

Yun Gao created FLINK-21084:
-------------------------------

             Summary: Allows tasks to report operator subtask finish state
                 Key: FLINK-21084
                 URL: https://issues.apache.org/jira/browse/FLINK-21084
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Checkpointing
            Reporter: Yun Gao


Once an operator is fully finished (e.g., all its subtasks are finished) in one checkpoint, the state need to be recorded to skip the execution of this operator after recovery. Thus we should allow operators to report finished state so that CheckpointCoordinator could identify fully finished operators for each checkpoint.
