Description

After taking a snapshot against a table with mob file data, the SnapshotInfo tool is not able to find the mob files even though they are present in the proper place. (<hbase>/mobdir/data/dfault/<table>/<region>/....)

Here's an example command line execution:

[jon@a1210 hbase]$ bin/hbase org.apache.hadoop.hbase.snapshot.SnapshotInfo -snapshot test -files
....
       - IntegrationTestIngestWithMOB/e9b5d936e7f55a4f1c3246a8d5ce53c2/test_cf/e75380c6db50db845dbdee48ab49381420141205f87d1b47b0f446c7acb3fa0656fa8a57 (NOT FOUND)

**************************************************************
BAD SNAPSHOT: 145 hfile(s) and 0 log(s) missing.
              0 hfile(s) corrupted.
**************************************************************
54 HFiles (54 in archive), total size 973.6 M (0.00% 0 shared with the source table)
0 Logs, total size 0

The missing files are actually present, it is likely that the snapshot tool doesn't know to look in the mob dir.
