ndbcluster引擎表同步到innodb引擎报错Error 'Unknown storage engine 'ndbcluster'
ndbcluster引擎表同步到innodb引擎报错Error 'Unknown storage engine 'ndbcluster'
环境是 ndbcluster集群环境到innodb环境的复制环境
在master上执行CREATE TABLE t3 (id int unsigned NOT NULL auto_increment PRIMARY KEY) ENGINE=ndbcluster;
在slave查看发现复制Slave_SQL_Running停止了，如下

解决ndbcluster表到innodb引擎同步方法如下：
在master设置默认的存储引擎
default-storage-engine=ndbcluster
在创建表的时候不要显式指定存储引擎
mysql> use myslave;
Database changed
mysql>
mysql> CREATE TABLE t2 (id int unsigned NOT NULL auto_increment PRIMARY KEY);
Query OK, 0 rows affected (0.81 sec)
查看slave发现同步正常
