Titan Hadoop小精灵配置问题

我试图通过遵循Titan文档，让Titan与Tinkerpop 3.0.1 Hadoop Gremlin一起工作。我基本上是从下载页面下载titan-1.0.0-hadoop1

我几乎完全按照文档进行操作，唯一的区别是我使用的是HBase支持的图形，而不是文档中使用的Cassandra图形。我确信我的“titan hbase cluster.properties”文件没有错误，可以在hbase中读/写而不会出现任何问题

因此，根据Titan文档，我在gremlin控制台中发出以下命令：

         \,,,/
         (o o)
-----oOOo-(3)-oOOo-----
plugin activated: aurelius.titan
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities

gremlin> graph.compute(SparkGraphComputer).program(blvp).submit().get()

运行这些命令后，我得到以下警告和错误字符串
