Невозможно запустить кластер Cassandra после настройки конфигурации SSL

Я настроил шифрование клиент-узел, используя ссылку http://cloudurable.com/blog/cassandra-ssl-cluster-setup/index.html

cassandra version 2.1.16
java version jdk1.8.0_131
JCE version JAVA 8
netty-all-4.0.23.Final
Python version Python 2.7.5

кто-нибудь, пожалуйста, помогите мне, какой шаг неправильный? а эти версии совместимы?
