Ilias Kapouranis commented on HAMA-833:
---------------------------------------
if(getSuperstepCount() == 1){
if(getVertexID().toString().equals("1")){
voteToHalt();
}
} else if(getSuperstepCount() == 2){
System.out.println(getNumLastAggregatedVertices(0));
} else if(getSuperstepCount() == 3){
System.out.println(getNumLastAggregatedVertices(0));
}
So here we choose the vertex with id 1 to halt. At superstep 2 and 3 we print
the number of vertices that were aggregated before each superstep.
If we insert 10 nodes, at superstep 2 we will see that it prints 10. This means
that even though the node halted, it was aggregated! But then at superstep 3,
we will see that the number goes to 9.

> 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?
