See http://dev.mysql.com/tech-resources/articles/mysql-cluster-50.html

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.
