Java 弹性搜索的土卫六载荷问题

我正在使用以下代码加载Titan：

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();

使用gradle加载依赖项：

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

我的项目目录是：

/home/ray/IdeaProjects/BAG-图形数据库的拜占庭容错体系结构/

我的titan位于文件夹“titan”中的项目目录中 这就是我在目录变量中设置的

仍然在启动时，它总是崩溃：

您似乎有类路径问题：

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，而Elasticsearch 1.5.1又依赖于Lucene 4.10.4，Lucene 4.10.4有一个不推荐的字段

org.apache.Lucene.util.Version.Lucene\u 3\u 6

。此字段在Lucene的更高版本中被删除。你需要检查你的类路径，确保你拉入的是正确版本的Lucene。

你应该更具体地说明你的Titan依赖项，这样你就不会拉入意外的工件。不要使用

titan all

，请尝试以下方法：

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

您不需要显式地包括

gremlincore

，因为它是

titan core

的依赖项，但如果您添加了它，它应该与titan 1.0使用的一致：

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

已更新

您以前失败的尝试可能创建了存储在

目录下的无效图形实例。在尝试使用同一目录创建新图形之前，必须递归删除
目录

Elasticsearch索引后端不适用于
index.search.DIRECTORY
配置（请注意这种情况）。这是堆栈跟踪的相关部分：

已忽略index.search.DIRECTORY的配置项，因为它未映射到选项
java.lang.IllegalArgumentException:命名空间[root.index]：目录中的未知配置元素

您可以在Titan文档的第页中阅读有关各种Elasticsearch配置选项的更多信息

代替弹性搜索，考虑使用。它的配置看起来类似于BerkeleyJE storage，并且都非常适合单机版Titan
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();

还使用lucene的依赖项更新
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'

我还建议您首先尝试构建一个没有Neo4j、OrientDB、Sparksee和其他非Titan依赖项的Titan项目，以确保您有一个简单的项目，可以在没有任何依赖项冲突的情况下工作。
因此，“编译组：'com.thinkaurelius.Titan'，名称：'Titan all'，版本：'1.0.0'不再工作了，我必须手动拉取资源？我使用maven拉取titan all，类路径似乎还可以（这就是我从上面发布的信息中得到的信息）。我不使用ES和Lucene，因此我无法轻松验证Titan与Lucene的集成。您可能会从其他项目依赖项继承更新的Lucene版本。如果我尝试使用默认配置运行titan，也会发生这种情况。可能是其他人拉了Luscene或ES。我添加了我拉的内容。因此对于不同版本的Lucene。删除目录并更新依赖项解决了问题
compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0'
compile group: 'com.thinkaurelius.titan', name: 'titan-lucene', version: '1.0.0'
