使用教程中给出的以下命令：http://s3.thinkaurelius.com/docs/titan/0.5.0/hbase.html

TitanGraph graph = TitanFactory.build()
                .set("storage.backend","hbase")
                .open();

使用maven依赖项：

<dependency>
            <groupId>com.thinkaurelius.titan</groupId>
            <artifactId>titan-hbase</artifactId>
            <version>${titan.version}</version>
        </dependency>

显示以下错误

如果可能的话，你能告诉Cassandra同样的情况吗。
