在文档中似乎应该足以设置/ etc / defaults / dse来启用上述所有功能。意思是，还增加了SPARK的支持。此外，节点工具现在指示所有内容都已启动并运行，并且（单节点）群集的类型为Graph，Search，Analytics因此启用工作正常，但尝试使用分析会导致配置级别的异常，这可能是与火花配置有关。但那里没有任何记录。似乎其他人也坚持这个问题。
这是完整的例外：构造Graph / TraversalSource时遇到错误 - com.google.inject.ProvisionException：无法配置，请参阅以下错误：1）注入构造函数时出错，com.datastax.bdp.gcore.datastore.DataStoreException：Failed在com.datastax.bdp.graph.impl.DseGraphImpl。（DseGraphImpl.java:189）的com.datastax.bdp.graph.impl.GraphModule.configure（未知来源）执行statementb5807f0d-b1b0-4bc3-bd77-794d21725fbb（通过模块：com.datastax.bdp.graph.impl.DseGraphFactoryImpl $$ Lambda $ 1430/208354649 - > com.google.inject.util.Modules $ OverrideModule - > com.datastax.bdp.graph.impl.GraphModule）在定位com时.datastax.bdp.graph.impl.DseGraphImpl 1 error构造Graph / TraversalSource时遇到错误 - 当Spark未运行或无法检测到时，无法创建OLAP遍历源。
请注意，尝试使用studio或gremlin控制台中的graph-analytics查询时会收到此异常。 cassandra日志文件等没有特定的错误。此外，从dse服务的角度来看，一切似乎都是正确的，但事实上它实际上并不起作用。
这些是在播放一些常量后出现的错误：

好吧，有了这个日志，它变得越来越清晰。真正的罪魁祸首是这个消息：Failed to bind MasterRedirectingUI - 这意味着Spark Master无法启动，因为有人已经在侦听它正试图使用的端口 - 默认情况下它是7080，但它可以通过在SPARK_MASTER_WEBUI_PORT文件中设置spark-env.sh变量来覆盖（无论是在tarball安装中的resources/spark/conf，还是在/etc/dse/spark/中）。
检查没有其他进程正在侦听这些端口 - 您可以使用netstat -plnt执行此操作...
