                 Key: HBASE-10111

          Components: snapshots
    Affects Versions: 0.94.14, 0.96.0, 0.98.0
            Reporter: Matteo Bertozzi
            Assignee: Matteo Bertozzi
            Priority: Minor
             Fix For: 0.98.0, 0.96.1
         Attachments: HBASE-10111-v0.patch

To avoid assigning/opening regions with missing files, verify that the snapshot is not corrupted before restoring/cloning it.

In 96 a corrupted file in a region is "not a problem" since the assignment will give up after awhile.
In 94 having a corrupted file in a region means looping forever, on "enable",  until manual intervention. (Easy way to test this is create a table, disable it, add a corrupted reference file and enable the table to start looping: you can use echo "foo" > aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
