>
> When building the job model, the existing container locality is read, so that
> the task to container grouping can be calculated. However, the existing
> container locality mapping is incorrect, in that it always has one extra
> container than the job container count. If a grouper (e.g.
> GroupByContainerIds) uses the mapping to figure out the container models,
> then it might return the incorrect number of containers for the job model.
