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, which is then later represented as a SnapshotDiffReport. In later jiras we will add support to represent the SnapshotDiffReport to end users. was: 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.
