      Description

      ReplicationTargetChooser chooses targets by iteratively selecting random nodes first and then filtering good targets until the required number of targets are chosen. This code may require selecting random nodes multiple times, thus introducing multiple traversals of the given portion of the cluster map. This code can be improved by traversing the portion of the cluster map only once.
