通过Gremlin控制台将Titan图形数据库连接到Gephi [英] Connection of Titan graph DB to Gephi through Gremlin console
问题描述
我正在尝试通过gremlin控制台连接到gephi(0.9.1).我的泰坦数据库中有一张图.我还在gephi中启用了流服务器.通过gremlin我执行了以下命令:
I am trying to connect to gephi(0.9.1) through gremlin console. I have a graph in my titan database. I also have the streaming server enabled in my gephi. And through gremlin i executed the following commands:
- :插件使用tinkerpop.gephi
- g = TinkerFactory.createModern()
- :远程连接tinkerpop.gephi
所有这些都工作正常.但是当我运行最后一条命令时:
All these worked fine.But when i ran the last command:
:> g
我遇到以下错误:

Display stack trace? [yN]
而且我经常得到:
15:38:20.276 [Finalizer] DEBUG o.a.h.i.conn.DefaultClientConnection - Connection 0.0.0.0:60710<->127.0.0.1:8080 closed
我检查了打开的端口，还发现8080端口已打开.
I have checked for the opened ports, and i also found that 8080 port is opened.
推荐答案
请注意，自TinkerPop 3.2.1-SNAPSHOT起，直到最近，Gephi插件才与Gephi 0.9.x兼容.
Note that the Gephi Plugin was only recently made compliant with Gephi 0.9.x as of TinkerPop 3.2.1-SNAPSHOT a few days ago. As you are using Titan 1.0, I would guess that you have an older version. I would recommend going back to Gephi 0.8.x beta if you want everything to work seamlessly.
所有这些，您可能仍然可以使它正常工作. Gephi提供的默认工作空间不再是"workspace0"-现在从"1"开始索引.您可以执行以下操作来更改Gremlin遥控器使用的工作空间:
All that said, you might yet be able to get it to work. The default workspace that Gephi provides is no longer "workspace0" - it is now indexed starting at "1". You can change the workspace used by the Gremlin remote by doing:
:remote config workspace workspace1
这应该允许将数据发送到Gephi，并应在实验室"窗格中显示.您可能还没有可视化方面的问题.我发现在解决此问题时，没有将大小"，"x"和"y"属性自动设置为合理"的情况似乎阻止了可视化窗格显示顶点和边缘.我认为您需要将这些属性添加到要推到Gephi的任何图形中.我确实将补丁的大小设置为"10"，并且将x/y设置为随机浮动-将它们全部设置为零/零(即相同的位置)无效.
That should allow the data to be sent to Gephi and it should show in the "laboratory" pane. You may yet have problems with the visualization. I found that while fixing this problem that not auto-setting the "size", "x" and "y" properties to "sensible" things seemed to prevent the visualization pane from displaying the vertices and edges. I think that you would need to add those properties to any graph you wanted to push across to Gephi. The patch I did set the size to "10" and the x/y were set to a random float - setting them all to to zero/zero (i.e. the same positions) did not work.
以上所有解决方法说明主要用于提供信息.在下载Gephi 0.8.x时，这可能是一件很容易的事，而您无需做很多额外的工作.
All of the above workaround instructions are mostly for informational purposes. That's probably a lot of extra work that you don't need to do when downloading Gephi 0.8.x is a pretty easy course of action.
