> 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. The snapshot diff is represented as a SnapshotDiffReport internally. In later jiras we will add support to present the SnapshotDiffReport to end users.
