ChiaHung Lin commented on HAMA-431:
-----------------------------------
Some thoughts base what I have known so far, but I may be wrong (or miss the
point) and probably do not see the whole forest.

Each BSPPeer could periodically poll the AM if it can proceed to the next
superstep. ...

With polling, it seems that chances are the polling would not reach the
agreement (there could always have 1 process missing) in an unfortunate timing
case. Also, as the processes increase probably it would increase the loading
for master to deal with polling tasks.
In addition, my understanding is the integration with MRV2 would be just an
additional support so that MR job/ application can be submitted without
rewriting to use hama for computation.
