> This is a bug reported by [~ssreenivasan]:
> 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.
