Documented bugfix in the NDB-7.0.16 and 7.1.5 changelogs as follows:

        When adding multiple new node groups to a MySQL Cluster, it was
        necessary for each new node group to add only the nodes to be
        assigned to the new node group, create that node group using
        CREATE NODEGROUP, then repeat this process for each new node 
        group to be added to the cluster. The fix for this issue makes 
        it possible to add all of the new nodes at one time, and then 
        issue several CREATE NODEGROUP commands in succession.

Also noted this issue and its resolution in the Manual section covering online node addition.

Closed.
