在mysql cluster 测试环境的其中一个节点上（id=4 192.168.1.251）执行 select 操作抱

而在 另外一个节点 192.168.1.252上执行相同的语句是没有问题的。

回头去管理节点查看  ，发现管理节点机器挂了。

启动机器

解决办法是重启 节点 192.168.1.251sql节点。

\[mysqld(API)\]   2 node(s)  
id=4    @192.168.1.251  (mysql-5.5.30 ndb-7.2.12)  
id=5    @192.168.1.252  (mysql-5.5.30 ndb-7.2.12)

在管理节点中看到的结果如上。
