             Summary: Use snapshot path as source when using snapshot diff 
report in DistCp
                 Key: HDFS-8036
                 URL: https://issues.apache.org/jira/browse/HDFS-8036
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: distcp
    Affects Versions: 2.7.0
            Reporter: Jing Zhao
            Assignee: Jing Zhao


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.
