> from the list, running multiple MR over the same snapshot does not work
> {code}
> public static void copySnapshotForScanner(Configuration conf, FileSystem ..
>     RestoreSnapshotHelper helper = new RestoreSnapshotHelper(conf, fs,
>       manifest, manifest.getTableDescriptor(), restoreDir, monitor, status);
> {code}
> the problem is that manifest.getTableDescriptor() will try to clone the snapshot with the same target name. ending up in "file already exist" exceptions.
> we just need to clone that descriptor and generate a new target table name
