> 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.
