Review Comment:
I feel these should be not-null, but we can default to the Cassandra's
defaults:
```
/**
* Returns the commit log directory of the Cassandra instance. If not
set, the default directory is
* {@link #cassandraHomeDir()}/data/commitlog
*
* @return commitlog directory of the cassandra instance
*/
@NotNull
default String commitlogDir()
{
return String.format("%s/data/commitlog", cassandraHomeDir());
}
```

Review Comment:
I think we should disallow the cassandra home dir to be null.

Review Comment:
I don't really know what this maps to in the cassandra.yaml configuration.
Did I miss something?
