Hyunsik Choi commented on HAMA-199:
-----------------------------------
This issue is really important because our one aims at large scale processing that takes long time. If hama doesn't have this feature and at least one server is fault, we have to restart that processing.
Basically, this feature would be good to follow the fault tolerance model of the mapreduce, materializing immediate results into local storage. Actually, that model is not efficient, but that is robust. Later, we will improve this feature to be pipelined like mapreduce online.
