Daryn Sharp commented on HDFS-4131:
-----------------------------------
As a high level comment, shouldn't this be a more programmatic api? Ie. a list
of objects containing the path and the snapshot state? It should be up to a
tool to decide how to format the diff.
> Add a tool to print the diff between two snapshots and diff of a snapshot
> from the current tree
