我正在尝试将 titan-1.0.0-hadoop1 与 apache-cassandra-3.2 连接起来。
我正在使用以下" titan-cassandra-myfile.properties":
storage.cassandra-config-dir=titan-1.0.0- hadoop1/conf/cassandra/cassandra.yaml
storage.backend=cassandra
storage.hostname=localhost
当我使用gremlin执行以下命令时:
g=TitanFactory.open("/path to titan/ titan-1.0.0-hadoop1/conf/titan-cassandra-myfile.properties");
我收到以下错误:

当我使用与 apache-cassandra-1.2.5 和 titan-all-0.3.1 相同的配置时,上述配置可以正常工作并创建图表。< / p>
请就此提出一些解决方案,无论是兼容性问题还是我做错了。
谢谢, Laxmikant
答案 0 :(得分:4)
Titan 1.0 。我几乎可以肯定它与 Cassandra 3.x 不兼容,因为有一个存储引擎重写
