Googling the error brought me to:
https://github.com/ptaoussanis/carmine/issues/5
...which nicely points out that Snappy 1.0.5 fixes the issue (DSC 1.2.3 ships with snappy-java-1.0.4.1).

To quickly fix the issue, from $CASSANDRA_HOME:

cd lib
rm snappy-java-1.0.4.1.jar
wget https://snappy-java.googlecode.com/files/snappy-java-1.0.5-M4.jar
