【问题描述】：
我已经在 Ubuntu 中安装了 hadoop，并为 namenode 和 data node 创建了目录。但我无法看到 namnode 和数据节点没有运行。

但我可以看到两个目录都已创建。

对不起，我在核心站点 xml 中写错了。它现在工作了。hduser@sanjeebpanda:/usr/local/hadoop/etc/hadoop$ jps 12240 NameNode 12715 ResourceManager 13056 Jps 12565 SecondaryNameNode 12387 DataNode 5311 JobHistoryServer 12842 NodeManager

我无法找到 hdfs 路径。你能帮忙找到那个吗？我必须使用 hadoop fs -put 命令放置一个文件。我无法找到 direcotry.hduser@sanjeebpanda:/usr/local/hadoop/yarn_data/hdfs$ ls -ltr drwxr-xr-x 3 hduser hadoop 4096 Nov 9 21:13 namenode drwx------ 2 hduser hadoop 4096 11 月 9 日 21:14 数据节点
