Question

我试图建立一个基本的泰坦示例。在关注文档后，我尝试运行bin/gremlin-server.sh -i com.thinkaurelius.titan titan-all 1.0.0抛出;

Could not install the dependency: java.io.FileNotFoundException: /usr/share/titan/ext/titan-all/plugin/titan-all-1.0.0.jar (No such file or directory)

我也尝试过gremlin.sh;

root@ubuntu:/usr/share/titan# bin/gremlin.sh

         \,,,/

我已经确认groovy有文件;

root@ubuntu:/usr/share/titan# ls ~/.groovy/grapes/com.thinkaurelius.titan/titan-all/jars
titan-all-1.0.0.jar

所以现在我很难过..有没有人遇到过这个？

编辑：关于我如何来到这里的一些说明..

我的第一次尝试是按照文档使用全包zip文件...我将gremlin-server.yaml更改为;

graph: conf/titan-cassandra-es.properties

那扔了;

407  [main] WARN  org.apache.tinkerpop.gremlin.server.GremlinServer  - Graph [graph] configured at [conf/titan-cassandra-es.properties] could not be instantiated and will not be available in Gremlin Server.  GraphFactory message: Configuration must contain a valid 'gremlin.graph' setting
java.lang.RuntimeException: Configuration must contain a valid 'gremlin.graph' setting

好的，简单的谷歌搜索告诉我，我需要将此添加到conf / titan-cassandra-es.properties;

gremlin.graph=com.thinkaurelius.titan.core.TitanFactory

此时，我得到..

484  [main] WARN  org.apache.tinkerpop.gremlin.server.GremlinServer  - Graph [graph] configured at [conf/titan-cassandra-es.properties] could not be instantiated and will not be available in Gremlin Server.  GraphFactory message: GraphFactory could not instantiate this Graph implementation [class com.thinkaurelius.titan.core.TitanFactory]
java.lang.RuntimeException: GraphFactory could not instantiate this Graph implementation [class com.thinkaurelius.titan.core.TitanFactory]

这让我相信我错过了com.thinkaurelius.titan.core.TitanFactory。这很奇怪，因为$ TITAN_HOME / lib确实包含titan-all-1.0.0.jar。所以我假设（可能是错误的）我需要运行titan-all安装以使其实际加载罐子..

Answer 1

Titan的基本安装是解压缩titan-1.0.0-hadoop1.zip。就是这样！

从http://titandb.io

下载

http://s3.thinkaurelius.com/docs/titan/1.0.0/getting-started.html

它已与Titan插件一起打包，因此您无需将它们安装到Gremlin控制台或Gremlin服务器中。

如果您想尝试使用Titan Server，可以使用预打包的titan.sh脚本自动启动服务器上的Cassandra和Elasticsearch。

Answer 2

对于遇到这种陌生感的人，请阅读整个堆栈跟踪。事实证明，在底部是waaay，它实际上有真正的问题;它无法连接到Cassandra因为我没有启用Thrift。

Titan的FileNotFoundException（titan-all）
