弹性搜索的 Titan 加载问题

【问题标题】：Titan loading problems with elastic search弹性搜索的 Titan 加载问题
【发布时间】：2017-04-02 22:55:48
【问题描述】：

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 - 图数据库的拜占庭容错架构/

我的泰坦在“泰坦”文件夹中的这个项目目录中 这就是我在 Directory 变量中设置的内容。

仍然在启动它总是崩溃：

    【解决方案1】：

    您应该更具体地了解您的 Titan 依赖项，以免引入意外的工件。不要使用titan-all，试试这样的：

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

    您不需要显式包含gremlin-core，因为它是titan-core 的依赖项，但是如果您添加它，它应该与Titan 1.0 使用的TinkerPop version 对齐：

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

    更新

    您之前的失败尝试可能创建了存储在DIRECTORY 下的无效图形实例。在尝试使用同一目录创建新图形之前，您必须递归删除 DIRECTORY。

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

    忽略 index.search.DIRECTORY 的配置条目，因为它没有映射到选项 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 Chapter 22 中阅读有关各种 Elasticsearch 配置选项的更多信息。

    考虑使用Lucene，而不是 Elasticsearch。它的配置看起来类似于 BerkeleyJE 存储，两者都非常适合单机 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();

    同时更新 build.gradle 对 lucene 的依赖：

    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，以确保您拥有一个没有任何依赖项冲突的简单项目。

    • 删除目录并更新依赖解决了问题
    【解决方案2】：

    您似乎遇到了类路径问题：

    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，后者又依赖于具有已弃用字段 org.apache.lucene.util.Version.LUCENE_3_6 的 Lucene 4.10.4。该字段在 Lucene 的更高版本中被删除。您需要检查您的类路径并确保您使用的是正确版本的 Lucene。

    【讨论】：

    • 所以“编译组：'com.thinkaurelius.titan'，名称：'titan-all'，版本：'1.0.0'”不再起作用，我必须拉资源手动？
    • 我使用 maven 引入了 titan-all，并且类路径似乎没问题（这就是我从上面发布的信息中获得信息的地方）。我不使用 ES 和 Lucene，因此无法轻松验证 Titan 与 Lucene 的集成。您可能会从您正在引入的其他项目依赖项中继承更新的 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。可能是别人拉 Luscene 或 ES。
    • 我添加了我要拉的东西。
    • 所以 check your dependency tree 用于不同版本的 Lucene。
