Some reasons I can come up with: - it would be hard to have tunable read/consistencies/replicas when interfacing with a file system. - data locality support would require strong coupling to the distributed file system interface (if at all possible given that certain sstables should live on the same data node). - operator complexity both administering a distributed file system as well as a Cassandra cluster. This was a personal reason why I chose Cassandra instead of HBase for a project.
