Examples with MembershipService org.onosproject.cluster.MembershipService used on opensource projects

Example 1 with MembershipService

use of org.onosproject.cluster.MembershipService in project onos by opennetworkinglab.

the class MembershipsListCommand method doExecute.

@Override
protected void doExecute() {
    MembershipService service = get(MembershipService.class);
    ClusterAdminService clusterService = get(ClusterAdminService.class);
    if (outputJson()) {
        print("%s", json(service));
    } else {
        service.getGroups().forEach(group -> {
            List<Member> members = newArrayList(group.members());
            print("-------------------------------------------------------------------");
            print("Version: %s, Members: %d", group.version(), members.size());
            members.sort(MEMBERSHIP_COMPARATOR);
            members.forEach(member -> {
                Optional<ControllerNode> controllerNode = Optional.ofNullable(clusterService.getNode(member.nodeId()));
                if (!controllerNode.isPresent()) {
                    print(" id=%s, version=%s, self=%s", member.nodeId(), member.version(), member.equals(service.getLocalMember()) ? "*" : "");
                } else {
                    ControllerNode node = controllerNode.get();
                    print(" id=%s, ip=%s, tcpPort=%s, state=%s, self=%s", member.nodeId(), node.ip(), node.tcpPort(), clusterService.getState(node.id()), member.equals(service.getLocalMember()) ? "*" : "");
                }
            });
            print("-------------------------------------------------------------------");
        });
    }
}

Example 2 with MembershipService

use of org.onosproject.cluster.MembershipService in project onos by opennetworkinglab.

the class StorageManager method eventuallyConsistentMapBuilder.

@Override
public <K, V> EventuallyConsistentMapBuilder<K, V> eventuallyConsistentMapBuilder() {
    checkPermission(STORAGE_WRITE);
    // Note: NPE in the usage of ClusterService/MembershipService prevents rebooting the Karaf container.
    // We need to reference these services outside the following peer suppliers.
    final MembershipService membershipService = this.membershipService;
    final ClusterService clusterService = this.clusterService;
    final NodeId localNodeId = clusterService.getLocalNode().id();
    // Use the MembershipService to provide peers for the map that are isolated within the current version.
    Supplier<List<NodeId>> peersSupplier = () -> membershipService.getMembers().stream().map(Member::nodeId).filter(nodeId -> !nodeId.equals(localNodeId)).filter(id -> clusterService.getState(id).isActive()).collect(Collectors.toList());
    // If this is the first node in its version, bootstrap from the previous version. Otherwise, bootstrap the
    // map from members isolated within the current version.
    Supplier<List<NodeId>> bootstrapPeersSupplier = () -> {
        if (membershipService.getMembers().size() == 1) {
            return clusterService.getNodes().stream().map(ControllerNode::id).filter(id -> !localNodeId.equals(id)).filter(id -> clusterService.getState(id).isActive()).collect(Collectors.toList());
        } else {
            return membershipService.getMembers().stream().map(Member::nodeId).filter(id -> !localNodeId.equals(id)).filter(id -> clusterService.getState(id).isActive()).collect(Collectors.toList());
        }
    };
    return new EventuallyConsistentMapBuilderImpl<>(localNodeId, clusterCommunicator, persistenceService, peersSupplier, bootstrapPeersSupplier);
