My table already has engine 'ndbcluster'.

Here is my configuration:
config.ini file
[ndb_mgmd]
hostname=localhost
datadir=c:\Users\user1\my_cluster\ndb_data
NodeId=1
[ndbd default]
noofreplicas=2
datadir=c:\Users\user1\my_cluster\ndb_data
[ndbd]
hostname=localhost
datadir=c:\Users\user1\my_cluster\ndb_data
NodeId=3
[ndbd]
hostname=localhost
datadir=c:\Users\user1\my_cluster\ndb_data
NodeId=4
[mysqld]
hostname=localhost
NodeId=50
[api]
hostname=localhost

my.cnf file
[mysqld]
ndbcluster
datadir=c:\\Users\\user1\\my_cluster\\mysqld_data
basedir==c:\\Users\\user1\\mysqlc
