通过zookeeper查看配置信息已经加载到了，就是这里报错了。 谢谢开发者

自己调试一把看看，然后提交一个PR。 看报错是shutdown的钩子回调报错了。

这个问题解决没？ mycat 版本： Mycat-server-1.6.7.6 也遇到这问题 反而我用Mycat-server-1.6.5是好的，但是这个版本schema.xml配置有个问题，table中subTables无法保存到zk。

这个问题可以通过禁用 shutdown hook 来解决。 在 mycat/conf/log4j2.xml 文件中增加以下内容：

<Configuration shutdownHook="disable" ...>

测试的版本为：Mycat-server-1.6.7.4 文件已经修改，并提交了PR。#2876
