This seems to conflict with the statement from the cluster-limitations
docs. However, if you do it in single-user-mode, it works. Otherwise you
may get errors regarding invalid schema infos on other sql nodes, which
then have to be restarted (with the local ndb tables of the sql nodes
being deleted) to work again.
