Jing Zhao updated HDFS-4131:
----------------------------

    Description: 
This jira provides internal data structures and computation processes for calculating and
representing the diff between two snapshots, or the diff between a snapshot and the current
tree. 

Specifically, a new method getSnapshotDiffReport(Path, String, String) is added to FSNamesystem
to compute the snapshot diff.
