the class RaftPartitionGroup method buildPartitions.

private Collection<PartitionMetadata> buildPartitions(ClusterService clusterService) {
    int partitionSize = this.partitionSize;
    if (partitionSize == 0) {
        partitionSize = clusterService.getNodes().size();
    }
    List<NodeId> sorted = new ArrayList<>(clusterService.getNodes().stream().filter(node -> node.type() == Node.Type.CORE).map(Node::id).collect(Collectors.toSet()));
    Collections.sort(sorted);
    int length = sorted.size();
    int count = Math.min(partitionSize, length);
    Set<PartitionMetadata> metadata = Sets.newHashSet();
    for (int i = 0; i < partitions.size(); i++) {
        PartitionId partitionId = sortedPartitionIds.get(i);
        Set<NodeId> set = new HashSet<>(count);
        for (int j = 0; j < count; j++) {
            set.add(sorted.get((i + j) % length));
        }
