嗨，我正在尝试在 ubuntu 上安装 hadoop(单节点)。
我无法打开 localhost:50070。
当我吃午饭时，我得到了这个
6674 NodeManager
6825 Jps
6359 ResourceManager
我是 ubuntu 的新手，所以尽可能多地解释一下，非常感谢。

最佳答案
如果 tmp 目录处于一致状态，请检查日志
日志文件位置:$HADOOP_HOME/logs/hadoop-*-namenode-**.log
您可能会在日志文件中看到一些内容
2016-12-10 00:59:55,718 错误 org.apache.hadoop.hdfs.server.namenode.NameNode:无法启动名称节点。
org.apache.hadoop.hdfs.server.common.InconsistentFSStateException:目录/tmp/dfs/name处于不一致状态:存储目录不存在或不可访问。
在 core-site.xml 中声明 tmp 目录，然后格式化 namenode。
我希望它会帮助你
