[Shang Yuanchun (Jira)]

Piotr Nowojski created FLINK-18431:
--------------------------------------

             Summary: Provide default empty implementation of notifyCheckpointAborted
                 Key: FLINK-18431
                 URL: https://issues.apache.org/jira/browse/FLINK-18431
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
    Affects Versions: 1.11.0
            Reporter: Piotr Nowojski
             Fix For: 1.11.0


There was some confusion during reviewing of FLINK-8871 and {{org.apache.flink.runtime.state.CheckpointListener#notifyCheckpointAborted}} was left without a default implementation, that's braking backward compatibility. Default empty implementation of this method should be provided.
