本文介绍了泰坦加载弹性搜索的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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（）;
加载依赖关系与gradle：
编译组：'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架构/
我的巨人在这个项目目录中的文件夹TITAN
这就是我在目录变量中设置的。
仍然开始总是崩溃：

解决方案
你应该更具体的是你的Titan依赖你不要拉入意外的文物。而不是使用 titan-all ，请尝试这样：
compile group：'com.thinkaurelius.titan'，name：'titan-berkeleyje'，version：'1.0.0'
compile group：'com.thinkaurelius.titan'，name：'titan-es'，version： '1.0.0'
您不需要包含 gremlin-core ，因为它是依赖于 titan-core ，但是如果你添加它，它应该与：
compile group：'org.apache.tinkerpop'，name：'gremlin-core'，version：'3.0.1-incubating'
更新
您以前的失败尝试可能会创建一个存储在 DIRECTORY 下的无效图形实例。在尝试使用相同目录创建新图表之前，您必须递归删除 DIRECTORY 。
弹性搜索索引后端不使用 index.search.DIRECTORY 配置（注意情况）。这是堆栈跟踪的相关部分：
您可以阅读更多关于Titan文档的中的各种弹性搜索配置选项。
而不是Elasticsearch，请考虑使用。它的配置看起来类似于BerkeleyJE存储，并且都非常适合单机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（）;
还要更新 build.gradle 对于lucene：
编译组：'com.thinkaurelius.titan'，name：'titan-berkeleyje'，version：'1.0 .0'
编译组：'com.thinkaurelius.titan'，name：'titan-lucene'，version：'1.0.0'
我还建议尽量建立一个没有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，没有任何依赖冲突。
I'm using the following code to load 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();
loading dependencies with gradle:
compile group: 'com.thinkaurelius.titan', name: 'titan-all', version: '1.0.0'
My project directory is:
/home/ray/IdeaProjects/BAG - Byzantine fault-tolerant Architecture for Graph database/
my titan is in this project directory in the folder "TITAN"That's what I set in the Directory variable.
Still on start it always crashes:

解决方案
You should be more specific on your Titan dependencies so you don't pull in unintended artifacts. Instead of using titan-all, try something like this:
compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0'
compile group: 'com.thinkaurelius.titan', name: 'titan-es', version: '1.0.0'
You should not need to include gremlin-core explicitly because it is a dependency of titan-core, however if you do add it, it should be aligned with the TinkerPop version that Titan 1.0 uses:
compile group: 'org.apache.tinkerpop', name: 'gremlin-core', version: '3.0.1-incubating'
Updated
Your previous failed attempts have likely created an invalid graph instance stored under DIRECTORY. You must recursively remove DIRECTORY before attempting to create a new graph using the same directory.
Elasticsearch indexing backend does not work with a index.search.DIRECTORY configuration (note the case). This is the relevant part of the stack trace:
You can read more about the various Elasticsearch configuration options in Chapter 22 of the Titan documentation.
Instead of Elasticsearch, consider using Lucene. Its configuration looks similar to BerkeleyJE storage, and both are well-suited for a single-machine 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();
Also update build.gradle with the dependency for lucene:
compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0'
compile group: 'com.thinkaurelius.titan', name: 'titan-lucene', version: '1.0.0'
I'd also recommend trying to build a Titan project without Neo4j, OrientDB, Sparksee, and other non-Titan dependencies first to ensure you have a simple project that works without any dependency conflicts.
