泰坦加载弹性search的问题

我正在使用下面的代码来加载泰坦:

TitanFactory.Builder config = TitanFactory.build(); config.set("storage.backend", "berkeleyje"); config.set("storage.directory", DIRECTORY); //config.set("storage.conf-file", "file:////" + DIRECTORY + "/cassandra/cassandra.yaml"); config.set("index." + INDEX_NAME + ".backend", "elasticsearch"); config.set("index." + INDEX_NAME + ".DIRECTORY", DIRECTORY + File.separator + "es"); config.set("index." + INDEX_NAME + ".elasticsearch.local-mode", true); config.set("index." + INDEX_NAME + ".elasticsearch.client-only", false); graph = config.open(); 

用gradle加载依赖关系:

 compile group: 'com.thinkaurelius.titan', name: 'titan-all', version: '1.0.0' 

我的项目目录是:

/ home / ray / IdeaProjects / BAG – 拜占庭容错架构for Graph数据库/

我的泰坦是在这个项目目录中的文件夹“TITAN”这就是我在目录variables中设置。

仍然在开始它总是崩溃:

我的gradle文件:

 testCompile group: 'junit', name: 'junit', version: '4.11' compile files('libs/BFT-SMaRt.jar') compile "org.neo4j:neo4j-enterprise:${neo4jVersion}" compile group: 'commons-codec', name: 'commons-codec', version: '1.5' compile group: 'io.netty', name: 'netty-all', version: '4.0.36.Final' compile group: 'com.thinkaurelius.titan', name: 'titan-all', version: '1.0.0' compile group: 'com.sparsity', name: 'sparkseejava', version: '5.2.0' compile group: 'com.orientechnologies', name: 'orientdb-graphdb', version: '2.2.11' compile group: 'org.jboss.spec.javax.ws.rs', name: 'jboss-jaxrs-api_2.0_spec', version: '1.0.0.Final' compile group: 'com.esotericsoftware', name: 'kryo', version: '4.0.0' compile 'com.intellij:annotations:+@jar' compile group: 'org.apache.tinkerpop', name: 'gremlin-core', version: '3.0.0.M9-incubating' 

    你应该对你的Titan依赖关系更具体,所以你不要引入意想不到的工件。 而不是使用titan-all ,尝试这样的事情:

     compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0' compile group: 'com.thinkaurelius.titan', name: 'titan-es', version: '1.0.0' 

    你不需要明确地包含gremlin-core因为它是titan-core的依赖,但是如果你添加它,它应该与Titan 1.0使用的TinkerPop版本对齐:

     compile group: 'org.apache.tinkerpop', name: 'gremlin-core', version: '3.0.1-incubating' 

    更新

    您之前失败的尝试可能会在DIRECTORY下创建一个无效图表实例。 在尝试使用相同目录创建新图形之前,必须递归移除DIRECTORY

    Elasticsearch索引后端不能使用index.search.DIRECTORY配置(注意大小写)。 这是堆栈跟踪的相关部分:

    由于index.search.DIRECTORY没有映射到一个选项,因此忽略了配置条目java.lang.IllegalArgumentException:命名空间[root.index]中的未知配置元素:DIRECTORY

    您可以在Titan文档的第22章中阅读关于各种Elasticsearch配置选项的更多信息。

    而不是Elasticsearch,考虑使用Lucene 。 它的配置看起来与BerkeleyJE存储相似,都非常适合单机泰坦。

     TitanFactory.Builder config = TitanFactory.build(); config.set("storage.backend", "berkeleyje"); config.set("storage.directory", DIRECTORY + File.separator + "berkeleyje"); config.set("index." + INDEX_NAME + ".backend", "lucene"); config.set("index." + INDEX_NAME + ".directory", DIRECTORY + File.separator + "lucene"); graph = config.open(); 

    同时更新与lucene依赖的build.gradle

     compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0' compile group: 'com.thinkaurelius.titan', name: 'titan-lucene', version: '1.0.0' 

    我也建议尝试构建一个没有Neo4j,OrientDB,Sparksee和其他非Titan依赖的Titan项目,以确保你有一个简单的项目,没有任何依赖冲突。

    您似乎有一个类路径问题:

     Caused by: java.lang.NoSuchFieldError: LUCENE_3_6 at org.elasticsearch.Version.(Version.java:43) 

    Titan-es 1.0.0依赖于Elasticsearch 1.5.1,它依赖于Lucene 4.10.4,它有一个不赞成的字段org.apache.lucene.util.Version.LUCENE_3_6 。 这个字段在后来的Lucene版本中被删除了。 您需要检查您的类路径,并确保您正在使用正确版本的Lucene。
