The bindings use the default Hadoop settings (e.g. 64 or 128 MB chunks) when creating new files. The chunk size can also be specified on a per-file basis using the same interface as Hadoop. Additionally, while Hadoop doesn't provide an interface to configuration parameters beyond chunk size, we will also let users fully configure for any Ceph striping strategy. http://ceph.com/docs/master/dev/file-striping/
