Saumitra Shahapure commented on FLINK-2714:
-------------------------------------------
I have a question. In EnumTrianglesOpt.java
(https://github.com/apache/flink/blob/master/flink-examples/flink-java-examples/src/main/java/org/apache/flink/examples/java/graph/EnumTrianglesOpt.java)
line number 194, why is the vertex ordering being compared? Where is it
significant?
Also, as I understand, I am supposed to replace Datatypes from
EnumTrianglesDataTypes (Like Edge) to Gelly's native datatypes (which I am
already doing). In Gelly's Edge class, vertex datatype is not comparable. So
vertex1<vertex2 comparison is not possible.

> Key: FLINK-2714
> URL: https://issues.apache.org/jira/browse/FLINK-2714
> Project: Flink
> Issue Type: Task
> Components: Gelly
> Affects Versions: 0.10
> Environment:
> Reporter: Andra Lungu
> Assignee: Saumitra Shahapure
> Priority: Trivial
> Labels: newbie, starter
>
> Currently, the Gelly library contains two methods for counting the number of
> triangles in a graph: a vertex-centric version and a gather-apply-scatter
> version.
> This issue proposes the addition of a third library method based on this
> Flink example:
> https://github.com/apache/flink/blob/master/flink-examples/flink-java-examples/src/main/java/org/apache/flink/examples/java/graph/EnumTrianglesOpt.java
> The only modification needed is an extra reduce step that takes the
> enumerated triangles produced and yields a number.
