You really do not need much in java you can use the embedded server. Hector
wrap a simple class around thiscalled  EmbeddedServerHelper

basically starts up an embedded instance of cassandra and fools your
client/driver into using it.  It uses a non-standard port and you just need
to make sure you can set the port as a parameter into your client code.
