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

Hi, I may miss something.

You mean that the savepoint is completed successfully, but it should not be successful according to your analysis about the code ?

> When I trigger a savepoint with the Flink K8s operator, I verified for two sources (KafkaSource and MultiClusterKafkaSource) do not invoke snapshotState or notifyCheckpointComplete. This is easily reproducible in a simple pipeline (e.g. KafkaSource -> print). In this case, the savepoint is complete and successful, which is verified by the Flink Checkpoint UI tab and the jobmanager logs. e.g. `
> Triggering checkpoint 3 (type=SavepointType\{name='Savepoint', postCheckpointAction=NONE, formatType=CANONICAL})`
>  
> However, when the checkpoint occurs via the interval, I do see the sources checkpointing properly and expected logs in the output.
