Hi [~gaoyunhaii] ，your concern is correct. If restore from more earlier
checkpoints, the data will be at least once.
Hi [~liyu] ， I create a pull request to fix this defect here
https://github.com/apache/flink/pull/13377, could you help review if it is
acceptable?

> I meet the issue on flink-1.10.1. I use flink on YARN(3.0.0-cdh6.3.2) with
> StreamingFileSink.
> code part like this:
> {code}

> BucketAssigner<IN, String> assigner, String prefix) {
> return StreamingFileSink.forRowFormat(new Path(dir), new
> SimpleStringEncoder<IN>())
> .withRollingPolicy(
> DefaultRollingPolicy

> .withRolloverInterval(TimeUnit.HOURS.toMillis(2))

> {noformat}
> Due to this issue, it can not restart from the latest checkpoint and
> savepoint.
> Currently, my workaround is that we keep latest 3 checkpoint, and if it
> fails, I manually restart from penult checkpoint.
