Capture bad edges in Giraph

2015-06-22 Thread G.W.
Hi, Is there a way to capture bad edges in Giraph? Let me explain. I load vertices and edges separately (vip/eip). Am I able to know, when an edge is instantiated, that either of the vertex IDs did not exist in the vertex input file? Thanks!

Giraph + HBase – How to define HBase connectivity properties?

2015-05-11 Thread G.W.
Hi, org.apache.giraph.io.hbase has a couple of classes to load graph data from HBase. It has a HBaseVertexInputFormat class, but does anyone know how the HBase location is to be passed to this class? G

Undirected Vertex Definition and Reflexivity

2015-03-09 Thread G.W.
Hi Giraph Mailing List, I am writing about an undirected graph I am trying to move to Giraph. I have a question about the assumption Giraph makes when processing an input. Let V1 and V2, two vertices connected with a common edge. E1 defines an edge from V1 to V2. E2 defines an edge from V2 to V1.
