> The job coordinators need to call the StartpointManager#groupStartpointsPerTask method that handles the re-mapping. What needs to be implemented is when this method should be called in the job coordinators.
> YARN - ClusterBasedJobCoordinator should call the method before starting the processing containers.
> Standalone - The job coordinator should call the method when the leader is elected and before the other processors begin processing.
