--------------------------------

             Summary: Confirm checkpoint completed on task side would not fail the task if exception thrown out
                 Key: FLINK-18074
                 URL: https://issues.apache.org/jira/browse/FLINK-18074
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing, Runtime / Task
    Affects Versions: 1.11.0
            Reporter: Yun Tang
             Fix For: 1.11.0


FLINK-17350 let the task fail immediately once sync phase of checkpoint failed. However, the included commit ['Simplify checkpoint exception handling'|https://github.com/apache/flink/pull/12101/commits/a2cd3daceca16ae841119d94a24328b4af37dcd8] actually would not fail the task if the runnable of {{() -> notifyCheckpointComplete}} throwing exception out.
In a nutshell, this actually changes previous checkpoint exception handling.

Moreover, that part of code also affect the implemented code of {{notifyCheckpointAbortAsync}} when I introduce {{notifyCheckpointAborted}} on task side.
