我已经在基于云的服务器上安装了DSE 5.0来试用Gremlin工具。 DSE一般似乎没问题，相关端口可用等，但是当我在服务器命令行启动Gremlin控制台时，控制台打开OK，但是从教程中创建图表的基本第一步会引发错误：< / p>
gremlin> graph = TinkerFactory.createModern()
==>tinkergraph[vertices:6 edges:6]
gremlin> g = graph.traversal()
org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph cannot be cast to com.datastax.bdp.graph.api.DseGraphInternal

我还在本地计算机上安装了DSE 5.0。 Agan，DSE Cassandra似乎工作正常，当我尝试启动Gremlin控制台时，我得到了不同的错误：
dse gremlin-console

我找不到很多关于DSE 5.0 Graph的文档，在处理这样的错误时什么都没有。任何提示都会非常受欢迎。
