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

             Summary: Optimize the log information when the asynchronous part of checkpoint is canceled
                 Key: FLINK-27637
                 URL: https://issues.apache.org/jira/browse/FLINK-27637
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
    Affects Versions: 1.16.0
            Reporter: Lijie Wang


When the checkpoint is aborted due to expiration, the tasks whose asynchronous part of checkpoint is not completed will print following logs:
{code:java}
60477 [AsyncOperations-thread-1] INFO  org.apache.flink.streaming.runtime.tasks.AsyncCheckpointRunnable [] - DeclineSink (1/1)#0 - asynchronous part of checkpoint 2 could not be completed.
java.util.concurrent.CancellationException: null

    at java.lang.Thread.run(Thread.java:748) [?:1.8.0_241] {code}
 

Maybe we can optimize the logs to make it more friendly.
