You may need to do "chown -R cassandra /var/lib/cassandra /var/log/cassandra" .

It does not switch me to cassandra user[btw .. should this actually switch me to cassandra user?? ]. This user switching on my servers does not work for users like tomcat7 user, cassandra user but works for users that were manually created by user. Actually I tested this on two of my test servers but same results on both.
