Ted Malaska commented on SPARK-2173:
------------------------------------
Sorry I'm slow I just realized I don't even need superStep of master computer.
In the confines of Giraph I did need them to solve tree rooting, but in the
world of GraphX and can enter and exit Pregel when ever and how often I want.
So in the case of tree rooting. I would do max one super step of pregel to
broadcast to all my children to identify my roots then start a second pregel
with un bound super steps to root all the other vertices to the roots.
GraphX is so freeing in comparison to Giraph.
I will close the ticket now.

> In Girpah there is an idea of a master compute and a global superstep value
> you can access. I would like to add that to GraphX.
> Let me know what you think. I will try to get a pull request tonight.
