In the MySQL Management node I have:

ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)]	3 node(s)
id=2	@192.168.100.6  (mysql-5.7.25 ndb-7.6.9, Nodegroup: 0, *)
id=3	@192.168.110.16  (mysql-5.7.25 ndb-7.6.9, Nodegroup: 0)
id=4	@192.168.120.26  (mysql-5.7.25 ndb-7.6.9, Nodegroup: 0)

        Hi, I'm trying to setup kea 1.6 with MySQL NDB Cluster backend.
        Has someone experienced with them?
        
        I have changed the "ENGINE" in all create tables statements with
        ENGINE=NDBCLUSTER in the script dhcpdb_create.mysql however when
        I run it I get the following errors, I think, when created the
        tables keadhcp.dhcp4_pool and keadhcp.dhcp6_pool for the foreign
        keys they have:
        
        ...
        
        ERROR 1215 (HY000): Cannot add foreign key constraint
        Query OK, 0 rows affected (0,46 sec)

        Thanks in advanced for any help.
