             Summary: Edge e.getTargetVertexId() returns same instance
                 Key: GIRAPH-679
                 URL: https://issues.apache.org/jira/browse/GIRAPH-679
             Project: Giraph
          Issue Type: Bug
          Components: build
    Affects Versions: 1.1.0
            Reporter: Byungnam Lim


I was trying to remove all edges of each vertex in one superstep. Below is my code.

<code>
for (Edge<LongWritable, FloatWritable> e : vertex.getEdges()) {
      removeEdgesRequest(vertex.getId(), e.getTargetVertexId());
}
</code>
But it just removed only one edge in one superstep.

I debugged and found e.getTargetVertexId() returns one same instances so that makes the removedEdgeList.add() in VertexMutations class could not add the elements properly.

By creating new LongWritable instance for targetVertexId parameter, I could remove all edges in one superstep.



But I'm doubt that I found that the Edge e also gets one same instance during 'for' loop. Maybe the problem exists in vertex.getEdges() not e.getTargetVertexId().
