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