Matteo Bertozzi commented on HBASE-7354:
----------------------------------------

The tool gives you an idea of what is in the snapshot, and if the snapshot is 
valid.
.snapshotinfo dump, files dump and an idea of how many are in archive (extra 
space) and how many are shared with the table...
{code}
$ hbase org.apache.hadoop.hbase.snapshot.SnapshotInfo -snapshot test-snapshot 
-files

6 HFiles (6 in archive), total size 589.7k (0.00% 0.0 shared with the source 
table)
0 Logs, total size 0.0

The storefile case had if with two branches – this logfile link doesn't need to 
do this?

I've skipped this one, because I think that in 90% of the cases logs are in the 
archive.
