Edward J. Yoon commented on HAMA-833:
-------------------------------------

OKay, I finally understood. The values of inactive vertex should be excluded 
from aggregation. Right?

And, system has a bug.
{code}
      if (this.getSuperstepCount() == 0) {
        this.setValue(new DoubleWritable(1));
        if(this.getVertexID().equals(new Text("2"))) {
          this.setValue(new DoubleWritable(0.5));
        }
      } else if (this.getSuperstepCount() == 1) {
        // do nothing
      } else if (this.getSuperstepCount() == 2) {
        if(this.getVertexID().equals(new Text("2"))) {
          this.voteToHalt();
        }
      } else if (this.getSuperstepCount() == 3) {
        System.out.println("vertexID "+ this.getVertexID() +" : " + 
this.getLastAggregatedValue(0));
      }

Result:
vertexID 0 : 0.95
vertexID 4 : 0.95
vertexID 6 : 0.95
vertexID 8 : 0.95
vertexID 1 : 0.95
vertexID 3 : 0.95
vertexID 5 : 0.95
vertexID 7 : 0.95
vertexID 9 : 0.95
{code}

> We should handle more cases on the vertices, like:
> 1) voteToStop() : Immediately stop the vertex compute and suppress any 
> further calculations on top of that. (e.g. aggregation)
> 2) voteToTerminate(): Immediately stop the vertex compute, suppress any 
> further calculations on top of that and deactivate the vertex so even if any 
> message reaches it, will not come alive.
> Any comments?
