本文记录了在搭建Hadoop集群过程中遇到的防火墙未关闭问题，并提供了有效的解决方法，即确保使用root用户身份来关闭防火墙。

今天有同事在搭建另一个hadoop集群的时候，又出现了此问题，很简单。这里简单做个笔记。

就是防火墙没关闭的问题导致。

但是一定要注意：要切换成root用户才能有效关闭防火墙。

昨天在写代码的时候偶然报了这个错误。百度了一下，并没有适合我的答案（大部分都在说防火墙的问题，大家也可以先检查一下防火墙是否关闭）。 后来我在仔细检查代码中发现。 原来是我的代码中有一个bug。就是我会先检查所有报错节点的网络是否畅通，再检查报错节点的磁盘空间是不是满了。 这样就导致一种特殊情况：如果这个服务器不畅通，我是没办法去检查它的磁盘空间的，因为无法建立连接。 所以就在这里报错了。...
java.net.NoRouteToHostException No route to host的排查与解决思路分享

那问题肯定就出在这个datanode22中了，经过简单的测试发现，在HiveSQL的执行过程中，hadoop的心跳时间经常很大，整个hadoop集群的心跳超时时间设置为600S(这个值设置的非常大，其实是有点不合理的)，在web页面上能看见该节点的last contact为三百多秒，和宕机差不多。其实这个问题以前也发生过，但是发生的频率是极其低的，导致不能复现，二是也没有太好的办法，就单单一个No route to host有点无从下手，所以一直以来都没有搞清楚到底是什么原因。

在zookeeper搭建集群的时候遇到的这个坑。真是坑惨了我，弄了一晚上。吧经验分享给大家，希望能帮助到大家。 我搭建的zookeeper环境是三个服务器的环境。期初我启动了两个zookeeper查看状态后显示成功。但是最后一个是怎么都启动不起来。查看日志日志打印的错误是： zookeava.net.NoRouteToHostException: No route to host (Host unreachable) 这个错误一般是防火墙拦截导致的，但是我查看这个服务器的防火墙状态，我发现防火墙是关闭的呀。

这个原因一般是因为防火墙没关闭。 执行这个 systemctl stop firewalld.service 关闭防火墙等一下就好了 还有说用iptables命令 关闭 我这个没作用也贴下 service iptables status （查看防火墙状态） 解决：未关闭防火墙 1）永久性生效，重启后不会复原 关闭：chkconfig iptables off 2）立刻生效，重启后复原 关闭：service iptables stop ...
