----------------------------------

             Summary: implement vertex-subgraph on giraph
                 Key: GIRAPH-879
                 URL: https://issues.apache.org/jira/browse/GIRAPH-879
             Project: Giraph
          Issue Type: New Feature
            Reporter: Pavan Kumar
            Assignee: Pavan Kumar
         Attachments: vertexsub.patch

The idea is to create a vertex based subgraph given an input consisting of sampled/selected
vertices & the entire graph as edge input.

It filters out all edges that originate at a vertex that's not sampled/selected and writes
back to output
