[jira] [Created] (FLINK-6227) Introduce the DataConsumptionException for downstream task failure

zhijiang created FLINK-6227:
-------------------------------

             Summary: Introduce the DataConsumptionException for downstream task failure
                 Key: FLINK-6227
                 URL: https://issues.apache.org/jira/browse/FLINK-6227
             Project: Flink
          Issue Type: Sub-task
          Components: Network
            Reporter: zhijiang
            Priority: Minor


It is part of FLIP-1.

We define a new special exception to indicate the downstream task failure in consuming upstream data. 

The {{JobManager}} will receive and consider this special exception to calculate the minimum connected sub-graph which is called {{FailoverRegion}}. So the {{DataConsumptionException}} should contain {{ResultPartitionID}} information for {{JobMaster}} tracking upstream executions.
