Linux 启动Hadoop守护进程时连接被拒绝

我已使用2.6.0和以下配置创建了Hadoop群集：

1名称节点-名称节点、资源管理器、辅助名称节点、配置单元 8个数据节点-数据节点、节点管理器 安装后，它运行良好。1天后，它开始显示错误，如下所示：

只有资源管理器工作正常。但除此之外，没有任何服务正在运行。请帮我做这个。我一直在努力修复它。

看看这个SO链接是否有用：正如我看到的你提到的链接，我的集群不是这样的，因为我删除了/etc/hosts/中的所有内容：[root@Bigdata-016 ~]cat/etc/hosts 172.16.253.16 Bigdata-016 172.16.253.17 Bigdata-017 172.16.253.18 Bigdata-018 172.16.253.19 Bigdata-019 172.16.253.20 Bigdata-020 172.16.253.21 Bigdata-021 172.16.253.22 Bigdata-022 172.16.253.23 Bigdata-023 172.16.253.24 Bigdata-024没有机会在本地主机上绑定9000。我在本地主机上添加了127.0.0.0.1 localhost/etc/hosts虽然显示了相同的错误..看看这个SO链接是否有用：我试过了…但没有用
