I've played around with Ceph, I really like its features and strong consistency. But its weakness is that it is a complex beast to setup and maintain. If you think that configuring and maintaining a Hadoop cluster is hard, then Ceph is twice as hard. Ceph has really good documentation, but all the knobs you have to read and play around with is still too much. I prefer running a few ZFS servers, very easy to setup and maintain and much better performance. But if we reach Petabyte scale I think I would need something like Ceph.
