从文档看来，设置/ etc / defaults / dse以启用所有上述功能就足够了。 意味着，还添加了SPARK支持。 现在，节点工具还指示一切正常并且正在运行，并且（单节点）集群的类型为Graph，Search，Analytics 因此，启用工作正常，但是尝试使用分析会导致供应级别出现异常，这可能与Spark配置有关。但是那里没有任何文件。 似乎其他人也被这个问题困扰。
这是一个完整的例外： 构造Graph / TraversalSource时遇到错误-com.google.inject.ProvisionException：无法配置，请参见以下错误：1）注入构造函数com.datastax.bdp.gcore.datastore.DataStoreException的错误：无法执行语句b5807f0d-b1b0- com.datastax.bdp.graph.impl.DseGraphImpl。（DseGraphImpl.java:189）处的4bc3-bd77-794d21725fbb（com.datastax.bdp.graph.impl.GraphModule.configure（未知源）（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），同时查找com.datastax.bdp.graph .impl.DseGraphImpl 1错误 构造Graph / TraversalSource时遇到错误-无法运行Spark或无法检测到Spark时，无法创建OLAP遍历源。
请注意，尝试从Studio或gremlin控制台使用图分析查询时会收到此异常。 cassandra日志文件等中没有特定的错误。 此外，从dse服务的角度来看，一切似乎都是正确的，但实际上它实际上并不起作用。
这些是在使用某些常量后出现的错误：

答案 0 :(得分：0)
好的，有了这个日志，它变得越来越清晰。真正的罪魁祸首是以下消息：Failed to bind MasterRedirectingUI-这意味着Spark Master无法启动，因为有人已经在监听它试图使用的端口-默认情况下它是7080，但是它可能会被覆盖在文件SPARK_MASTER_WEBUI_PORT中设置spark-env.sh变量（在tarball安装的resources/spark/conf中或/etc/dse/spark/中）。
检查是否没有其他进程在这些端口上侦听-您可以使用netstat -plnt来执行此操作...
