J'ai essayé la mise à niveau Cassandra de 2.2.1 à 3.0.0 mais Cassandra ne démarre pas:mise à niveau de 2.2.1 à 3.0.0 échoue avec NullPointerException

Toute personne autre face à ce problème? J'ai également soulevé un problème ici: https://issues.apache.org/jira/browse/CASSANDRA-10788

Il semble que le code des fichiers existants prévu sous/répertoire de données, mais il ne peut pas trouver tout et appeler FileUtils .delete (null).
