David, When you start cassandra all the logs go to system.log normally in the /var/log/cassandra directory, so you should look there once it has started, to check everything is ok.
I assume you mean you ran nodetool status rather than nodetest. The nodetool command stores a history of commands in the directory ~/.cassandra, and from the stack trace you supply it looks like it is failing to create that directory. So I would check the file system permissions there.
