[jira] [Created] (GIRAPH-586) Customizable default vertex value

Alessandro Presta created GIRAPH-586:
----------------------------------------

             Summary: Customizable default vertex value
                 Key: GIRAPH-586
                 URL: https://issues.apache.org/jira/browse/GIRAPH-586
             Project: Giraph
          Issue Type: New Feature
            Reporter: Alessandro Presta
            Assignee: Alessandro Presta


When Giraph implicitly adds a vertex (e.g., during edge-based input or mutations), the vertex value is created using reflection, so it is default-initialized (e.g., a double will be 0.0).
For some algorithms, the default value might be something different, or even need to be read from the configuration at run-time.
