Question

我是泰坦的新手。

我正在使用ubuntu 12.04并使用从deb软件包安装的cassandra 2.0和ES 1.0。

我想让ES与泰坦合作。

gremlin> g = TitanFactory.open('/var/titan-cassandra-0.4.2/conf/titan-cassandra.properties') 
Could not find implementation class: com.thinkaurelius.titan.diskstorage.es.ElasticSearchIndex

storage.index.search.backend=elasticsearch
storage.index.search.hostname=127.0.0.1
storage.index.search.cluster-name=elasticsearch
storage.index.search.index-name=titan
storage.index.search.client-only=true
storage.index.search.sniff=false
storage.index.search.local-mode=false

那么......伟大的工作机会ES？

...更新

我现在使用4.2 titan-server-0.4.2.zip的服务器版本。现在我得到以下内容。

gremlin> g = TitanFactory.open('/var/titan-server-0.4.2/conf/titan-server.properties')

Answer 1

抱歉，我们无法及时解决您的问题。正如今天早上在邮件列表上所建议的那样，您可能存在依赖性问题，因为该错误表明titan-es-x.y.z.jar没有出现。你下载了什么版本的Titan？注意特征矩阵：

除非您下载Titan Server或Titan All，否则您不会打包ES。我们希望改进Titan 0.5的包装，使事情变得更容易。

Answer 2

您必须使用ElasticSearch 0.90.5，这与Titan 0.4.2使用的版本相对应。

Cassandra 2.0没问题，虽然Titan 0.4.2打包1.2。

titan- elasticseach and com.thinkaurelius.titan.diskstorage.es.ElasticSearchIndex
