Tommaso Teofili resolved HAMA-660.
----------------------------------
Resolution: Fixed
Assignee: Tommaso Teofili
> Make item cost calculation consistent in GD BSP
> -----------------------------------------------
>
> Key: HAMA-660
> URL: https://issues.apache.org/jira/browse/HAMA-660
> Project: Hama
> Issue Type: Improvement
> Affects Versions: 0.5.0
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Fix For: 0.6.0
>
>
> Cost per item is calculated without knowing the total number of items which
> is ok from an efficiency point of view but makes plugging of new cost
> functions bug prone since the total cost is then always divided by the number
> of items.
> It'd be good to have a 0th superstep where total number of items is read and
> then it's used in CostFunction#calculateCostPerItem
