Subject Re: Could hama start next computation after all vertexes vote to halt?

Sorry for late reply. I'm not sure but it's impossible with current
APIs. Basically no messages and inactivated vertices are job
termination condition by default.

If there's a clear example that shows how combining two jobs into one
is useful, we can consider to add it as a new feature.

How could I do this?
