You have to download apache-cassandra-2.0.10-bin.tar.gz and cassandra-jdbc-1.2.5.jar and cassandra-all-1.1.0.jar.

There is no need to install Cassandra on your local machine; just put the cassandra-jdbc-1.2.5.jar and the cassandra-all-1.1.0.jar files in the lib directory of unziped apache-cassandra-2.0.10-bin.tar.gz. Then you can use

 library(RJDBC)
 drv <- JDBC("org.apache.cassandra.cql.jdbc.CassandraDriver", 
              list.files("D:/apache-cassandra-2.0.10/lib",
              pattern="jar$",full.names=T))

That is working on my unix but not on my windows machine. Hope that helps.
