小白求助 :hadoop集群slaves上的NodeManager进程自动断

s100 master
s101 slaves
s102 slaves
s103 slaves

namenode -format 后start-all.sh
可以在slaves 看到
NodeManager 进程
但是在webui上 通过http://S100:50070看不到datenode节点信息

查看节点slaves上的
yarn-root-nodemanager-S101.log日志发现有报错信息

Connection refused,这样的错误一般是因为hosts文件和interfaces文件配置错误了,注意要区分127.0.0.1对应为localhost 然后主机名和相应IP对应好。将配置正确的hosts和interfaces文件分发到集群每个主机。检查完这些,可以试一下删除本地dir,重建本地dir,然后格式化集群,重启。
