             Summary: Further limit the explosion range of failover in hybrid shuffle mode
                 Key: FLINK-29769
                 URL: https://issues.apache.org/jira/browse/FLINK-29769
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.17.0
            Reporter: Weijie Guo


Under the current failover strategy, if a region changes to the failed state, all its downstream regions must be restarted. For ALL_ EDGE_BLOCKING type jobs, since they are scheduled stage by state, no additional overhead. However, for the hybrid shuffle mode, the upstream and downstream can both run at the same time. If the upstream task fails, we hope that it will not affect the downstream regions that do not consume it.
