Giraph 1.0.0 - Hadoop 0.20.2 (CDH3U5) The Giraph algorithm I'm developing dynamically retrieves adjacent vertices from within the Vertex.compute() method. The retrieval returns immediate neighbors and also relationships between the neighbors. For instance, for vertex A, the following edges could be retrieved... A->B A->C B->C
I'm trying to use the Vertex API to dynamically add vertices B and C and all three edges. I've managed to successfully add B and C, along with edges A->B and A->C (using Vertex.setEdges()). However, I'm having problems adding B->C using Vertex.addEdgeRequest(). It's saying... Already has missing vertex on this worker for B ...presumably because the addition of B to A's adjacency list also causes the vertex for B to be created. What's the proper way to update the graph?
