Just to clarify (since I mentioned HyperTable and Cassandra in that blog post), Facebook's own integration efforts are currently going into Hive+HBase alone, but for the Hive project as a whole, we'd be happy to see storage handlers beyond HBase. Someone from HyperTable has been working on one and asking questions on hive-user. At talks I have given, a number of people have expressed interest in Cassandra, but so far I haven't seen anyone take ownership on that after the GSoC project was a no-go.
Each technology has its own pros and cons, which I'll stay out of here, but I will say that I believe Hive can be useful as scaleout data integration/transformation technology even for stores which are unsuited for data warehousing.

HBase is the primary focus for integration with Hive (see http://www.cloudera.com/blog/2010/06/integrating-hive-and-hbase/, for example). Cassandra is a great choice for an OLTP application, but certainly not for a data warehouse.
