------------------------------------
> But it still leaves question marks on why this issue didn't show up earlier.
I guess it is some corner case, 1.16 did not trigger this problem when creating
checkpoint.
There are two possibilities for
[lowestRetained|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/StandaloneCompletedCheckpointStore.java#L149-L184]
= Long.Max:
# The checkpoints deque is empty. Will manually triggered checkpoints be added
to the deque?
# The chk-3's props.discardOnJobCancelled is true. This contradicts
CheckpointRetentionPolicy.RETAIN_ON_CANCELLATION, there may be some corner
cases that have been ignored.
Have you tried re-creating the 1.17 checkpoint? Can the problem be reproduced?
