Jake Mannix commented on GIRAPH-27:
-----------------------------------

Can anyone try to run something like the SimplePageRank stuff on some real data 
on a real cluster, to make sure that cross-JVM boundaries are properly working? 
 Hard to test the effect of this kind of change on that kind of thing in unit 
tests alone...

> Mutable static global state in Vertex.java should be refactored

> Vertex.java has a bunch of static methods for getting/setting global graph 
> state (total number of vertices, edges, a reference to the GraphMapper, etc). 
>  Refactoring this into a GraphState object, which every Vertex can hold onto 
> a reference to (yes, a tiny bit more memory per Vertex, but in comparison to 
> what's already in there...)
