Amazon web services JanusGraph:从EC2访问Amazon管理的Cassandra

我正在尝试设置JanusGraph以访问Amazon MCS。基础设施都是允许访问的，但我在配置步骤中遇到了困难

这是我正在为

janusgraph cql.properties

设置的配置：

storage.backend=cql
storage.hostname=cassandra.ap-southeast-1.amazonaws.com
storage.port=9142
storage.username=${CASSANDRA_USERNAME}
storage.password=${CASSANDRA_PASSWORD}
storage.cql.ssl.truststore.location=${CASSANDRA_TRUSTSTORE_LOCATION}
storage.cql.ssl.truststore.password=${CASSANDRA_TRUSTSTORE_PASSWORD}
storage.cql.ssl.enabled=true

Amazon MCS公开了端口9142，而不是9402

当我启动

gremlin server.sh

时，我可以看到以下输出：

2897 [main] INFO  com.datastax.driver.core.Cluster  - New Cassandra host /13.251.116.141:9042 added
2898 [main] INFO  com.datastax.driver.core.Cluster  - New Cassandra host /13.251.117.140:9042 added

尽管我已将端口设置为9142，但仍在添加端口为9042的新Cassandra主机，导致进程失败（因为9042不可用）。有什么我做错了吗？

Hm.那些端口为9042的机器可能会由您最初连接的机器向您报告。它将告诉您到目前为止它所知道的关于拓扑的一切。您是否有任何更具体的错误消息表明9042机器有问题？原来是AWS管理的Cassandra不支持JanusGraph的错误。但我记不起确切的细节：）
