我是Hadoop编程的新手。我已经安装了Hadoop，并按照这个link配置了单个集群

NameNode和DataNode运行正常，我可以复制HDFS上的文件。我可以通过HDFS的Web UI查看这些文件。但无法启动yarn ( start -yarn n.sh)。在日志中显示以下错误：

此错误表示端口中存在冲突。这个link建议了一个由Chris提出的解决方案，看起来可以解决这个问题。在这篇文章中，给出了一个完整步骤的链接，但看起来不是一个完整的link

请建议解决端口冲突的步骤

“java.net.BindException:地址已在使用中”是错误。您的8040端口空闲吗？似乎有什么东西在使用这个端口。如果其他程序正在运行，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
