> Reporter: Sushmitha Sreenivasan
> Assignee: Jing Zhao
> Priority: Minor
> Fix For: 2.8.0, 2.7.1, 3.0.0-alpha1

>
> 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.
