无法在主服务器上启动节点管理器（2个答案）
5年前关门了。
我是hadoop编程新手。我已经安装了hadoop，并按照这个链接配置了单集群
namenode和datanode运行正常，我可以在hdfs上复制文件。我可以通过hdfs的web ui查看这些文件。但无法启动Yarn（start yarn.sh）。日志中显示以下错误：

“java.net.bindexception:地址已在使用”是错误。你的8040端口有空吗？好像有什么东西在用这个端口。如果正在运行其他程序，请尝试更改端口，它应该可以工作。

为资源管理器使用正确的端口。请参阅此处http://docs.hortonworks.com/hdp2alpha/index.htm#appendix/ports_appendix/yarn_ports.htm
