COM.datastax.pilote.core.exception.InvalidQueryException: porte-clés de schéma de table non configuré

j'essaie de configurer les données de printemps avec cassandra. Mais je reçois une erreur de bellow, quand mon application se déploie dans tomcat.

quand je vérifie la connexion, elle est disponible sur le port donné. (127.0.0.1: 9042). J'ai inclus le traceur de pile et la configuration de ressort ci-dessous. Personne ne l'avoir idée sur cette erreur?

trace complète de la pile:
