MySQL Cluster work well but ndb_desc doesn't work
The cause of problem is no free nodeid to allocate for ndb_desc. ndb_desc will attempt to connect to management node as api node thus it need free node. To make free node for ndb_desc, management node need to have empty [mysqld] in global config config.ini (in production, I think the use empty [mysqld] is no safe because any client is possible to connect to managment node to get free nodeid)
