> TableSnapshotInputFormat restores the snapshot to a temporary directory that
> is outside the HBase's root directory so that it can read from the restored
> snapshot and also refer to hfiles in the actual root directory.
> In restoring the snapshot, we create new hfilelinks in the ephemeral
> location. Creating new hfile links also creates "back references" for GC.
> These back references are dangling since the restore location is outside the
> root dir, and requires a WRITE permission to the root dir (as opposed to just
> READ permission) to be able to run the MR-over-snapshot job.
