Attachment: GIRAPH-941.patch
> Rexster vertices read bug
> -------------------------
>
> Key: GIRAPH-941
> URL: https://issues.apache.org/jira/browse/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

> Problem:
> When Giraph reads from Titan DB via Rexster, it uses api like below
> /graphs/%s/tp/giraph/%s/rexster.offset.start=%s&rexster.offset.end=%s
> - 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.
> Reason:
> giraph-rexster/giraph-kibble/src/main/java/org/apache/giraph/rexster/kibble/IteratorVertex.java
> There was a vertex count variable, but it didn't work correctly. (it didn't
> increase)
> Solution:
> Add code to increase vertex count
