> HDFS-8036 makes the diff-based distcp use snapshot path as the source. This should also happen when
> # invalid snapshot names are provided as distcp parameters thus the diff report computation on the target cluster fails
> # there is modification happening in the target cluster thus {{checkNoChange}} returns false
> In other cases like source and target FS are not DistributedFileSystem, we should throw exceptions.
