> For an ordinary read-write job, the scan will check the numBuckets read from manifests against the current numBuckets, to avoid data corruption. See FLINK-27316.
>  
> For rescale-bucket rewrite, we should allow the rescale task to read the data as the old bucket number and rescale according to the new bucket number.
