如何将 Janusgraph 0.4.0 连接到 COSMOS DB（Cassandra API）？

Question

我正在尝试使用以下属性文件从 janusgraph（在 Azure VM 上）连接到 Azure Cosmos DB（Cassandra API）

janusgraph-cql.properties 文件

gremlin.graph=org.janusgraph.core.JanusGraphFactory
graph.set-vertex-id = false
storage.backend=cql
storage.hostname=xx.xx.xxx.xxxx
storage.port=10350
storage.cassandra.keyspace=janusgraph
storage.username=hipcosmosdb-cass
storage.password=***************
storage.cassandra.ssl.enabled=true
storage.cassandra.ssl.truststore.location=/data/certs/cacerts.jks
storage.cassandra.ssl.truststore.password=*****

我能够从同一个虚拟机连接到运行 java 快速启动代码的数据库。

快速启动代码配置文件

###Cassandra endpoint details on cosmosdb
cassandra_host=xxxxxxxxxxxxx
cassandra_port=10350
cassandra_username=hipcosmosdb-cass
cassandra_password=************
ssl_keystore_file_path=/data/certs/cacerts.jks
ssl_keystore_password=******

相关端口规则添加完毕，仍然出现如下错误。
