elasticsearch - titan- elasticseach和com.thinkaurelius.titan.diskstorage.es.ElasticSearchIndex

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。

我试图让ES与titan一起工​​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

所以..泰坦能干ES吗？

更新...

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

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

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

尽管Titan 0.4.2与1.2一起打包，但Cassandra 2.0还可以。
