    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.
