Subject [jira] [Created] (GIRAPH-941) Rexster vertices read bug
Date Tue, 12 Aug 2014 04:17:11 GMT
Seong-il Lee created GIRAPH-941:

             Summary: Rexster vertices read bug
                 Key: GIRAPH-941
             Project: Giraph
          Issue Type: Bug
         Environment: - Ubuntu 12.04
- Hadoop 1.2.1
- Giraph trunk
- Titan 0.4.4
            Reporter: Seong-il Lee
            Priority: Minor
         Attachments: GIRAPH-941.patch

When Giraph reads from Titan DB via Rexster, it uses api like below


- offset.start : index of start vertex
- offset.end : index of end vertex

Titan DB has 100 vertices and I want to read vertices 1 to 10.
So, I set
offset.start = 1
offset.end = 10

But, Rexster read whole vertices from Titan DB.

There was a vertex count variable, but it didn't work correctly. (it didn't increase)

Add code to increase vertex count
