Como conectar o Janusgraph 0.4.0 ao COSMOS DB (API Cassandra)?

Question

Estou tentando me conectar ao Azure Cosmos DB (API Cassandra) do janusgraph (no Azure VM) usando o arquivo de propriedades abaixo

O arquivo janusgraph-cql.properties

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=*****

Consigo me conectar ao banco de dados executando o código de início rápido java da mesma VM.

O arquivo de configuração do código de início rápido

###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=******

As regras de porta relevantes são adicionadas. No entanto, o erro abaixo permanece.
