fwiw, I read the instructions at contrib/word_count/README and it has like 3 manual steps, so using an embedded cassandra instance may simplify this into one single step and let the program do all setup and teardown it requires.

There's an example in contrib/word_count, as mentioned in NEWS.  Basic
hadoop knowledge is assumed. :)

Johan has been making fixes to the 0.6 branch that are not in beta2,
so you will probably want to get that from svn.

I've added to CHANGES in the 0.6 branch too, thanks for the heads up.

I also didn't see anything in JIRA explicitly about it.  Is there anywhere I can find further information?
