Ilias Kapouranis commented on HAMA-833:
---------------------------------------

Imagine we are at superstep 3 and node K votes to halt. He WILL BE aggregated at the next aggregation phase. But from superstep 4 and onward he will be inactive.

> 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?
