NodeManager 和 ResourceManager 未运行

Question

我是Hadoop编程的新手。我已经安装了Hadoop并配置了单个集群，点击此链接

NameNode和数据节点运行正常，我可以在HDFS上复制文件。我可以通过HDFS的Web UI看到这些文件。但无法启动纱线（start-yarn.sh）。在日志中显示以下错误：

此错误表示端口冲突。此链接建议克里斯的解决方案，看起来可以解决您的问题。在这篇文章中，给出了一个完整的步骤链接，但看起来不是一个完整的链接

请建议解决端口冲突的步骤

Answer 1

" java.net.BindException： Address 已在使用中"是错误。您的 8040 端口是免费的吗？似乎有什么东西正在使用这个端口。如果正在运行其他内容，请尝试更改端口，它应该可以工作。

Answer 2

为资源管理器使用正确的端口。参考这里http://docs.hortonworks.com/HDP2Alpha/index.htm#Appendix/Ports_Appendix/YARN_Ports.htm
