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.
