我安装了 haddop-2.6.0 并遵循了 Apache 站点 http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-common/SingleCluster.html 中的单集群说明。
当我尝试使用以下命令启动 ResourceManager 时
$sbin/start-yarn.sh
我在控制台中没有收到任何错误，但是当我看到资源管理器日志时却看到了错误。这是日志

我在 hadoop-2.6.0/etc/hadoop/文件夹中有文件 capacity-scheduler.xml
不确定哪里出了问题。
我可以使用 start-dfs 启动名称节点，没有任何问题。
jps显示如下
9379 SecondaryNameNode
9057 NameNode
9199 DataNode
12861 Jps
谢谢
最佳答案
您的配置目录或类路径中缺少 capacity-scheduler.xml。您可以从 here 中提取它的默认示例副本
关于hadoop - 无法启动 ResourceManager (capacity-scheduler.xml) 找不到 hadoop 2-6.0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28357130/
