> Support HDFS snapshots. It should support creating snapshots without shutting 
> down the file system. Snapshot creation should be lightweight and a typical 
> system should be able to support a few thousands concurrent snapshots. There 
> should be a way to surface (i.e. mount) a few of these snapshots 
> simultaneously.
