Hadoop 使用start-dfs.sh时出现问题

我使用此链接创建了一个4节点集群：，但一旦我到达启动hadoop集群的部分，就会出现如下错误：

$HADOOP_HOME/sbin/start-dfs.sh

以下是我运行jps时发生的情况：

我不确定我在配置等方面哪里出了问题。我不熟悉hadoop和map reduce，所以请保持简单。

这是一个与权限相关的问题，看起来您用来启动hadoop服务的用户（我想是ubuntu）在日志目录（/usr/local/hadoop）中没有写权限-您应该将hadoop文件复制为sudo/root。尝试递归地更改Hadoop主目录的所有权，或授予/usr/local/Hadoop/logs目录的写访问权

chown -R ububunt:ubuntu /usr/local/hadoop  

或

就这样。谢谢。如果我有代表，我会+1。酷！！别担心。开始为社区做贡献，以获得足够的声誉。

chmod 777 /usr/local/hadoop/logs
