As far as I know the CassandraFS google code project has nothing to do with the current implementation in Brisk (although I really have no idea about that).
Some additional information about CFS in Brisk can be found in the presentations from Cassandra SF 2011 [1]. There is a nice presentation titled "Introduction to Brisk" that reviews some of the HDFS compatibility.

Now CassandraFS on google.code seems inactive now. I don't see any release out of that. Do you know if Brisk is considered stable at all or still very experimental? thanks Ruby On Thu, Aug 25, 2011 at 12:44 PM, Robert Jackson <robe...@promedicalinc.com> wrote: > I believe this is conceptually similar to what Brisk is doing under > CassandraFS (HDFS compliant file system on top of cassandra). > > Robert Jackson > > [1] - https://github.com/riptano/brisk > ________________________________ > From: "Sasha Dolgy" <sdo...@gmail.com> > To: user@cassandra.apache.org > Sent: Thursday, August 25, 2011 12:36:21 PM > Subject: Re: Is Cassandra suitable for this use case? > > You can chunk the files into pieces and store the pieces in Cassandra... > Munge all the pieces back together when delivering back to the client... > > On Aug 25, 2011 6:33 PM, "Ruby Stevenson" <ruby...@gmail.com> wrote: >> hi Evgeny >> >> I appreciate the input.
