> When using snapshot diff report for distcp (HDFS-7535), the semantic should be apply
the diff to the target in order to sync the target with source@snapshot2. Therefore after
syncing based on the snapshot diff report, we should append the name of snapshot2 to the original
source path and use it as the new source name.
