Yeah, we tried to catch when Snappy couldn't load (and deactivate it when that happens) but apparently we've missed a few of the exceptions that can be thrown in that case. I've created https://issues.apache.org/jira/browse/CASSANDRA-4400 to fix that. If you could try the patch on that issue and check it works for you that would be awesome since I don't have a Raspberry Pi myself to test.
