Hadoop安装问题：

Question

我遵循这教程来安装Hadoop。不幸的是，当我运行star-all.sh脚本时，控制台上打印了以下错误：

hduser@dennis-HP:/usr/local/hadoop/sbin$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
hadoop config script is run...

当我执行JPS命令时，引发了以下错误

hduser@dennis-HP:/usr/local/hadoop/sbin$ jps
3802 Jps

我是hadoop的新手，所以请告诉我一篇文章，它将帮助我安装hadoop而不存在任何问题。

或者，如果可能(或者更好)解决所面临的问题，请让我知道哪里出了问题，以及如何解决？

Answer 1

当前用户对/usr/local/hadoop的权限有限。尝试更改权限。

sudo chmod 777 -R /usr/local/hadoop/

Answer 2

请使用命令chmod或chown在文件夹上正确设置权限。

Hadoop提供单独的节点来启动和停止服务，即Hadoop-daemon.sh启动节点。

同样，也有启动/停止纱线的脚本。下面的文章详细介绍了安装Apache Hadoop http://www.hadoopstrata.com/staticpost?postNbr=7的步骤

Answer 3

老实说，我不知道我为什么会犯这个错误。但是，我使用askUbuntu中提供的说明删除了整个安装，并使用官方站点- 这里中描述的安装方法重新安装了它。

但您是对的@Krishna，日志是在安装后自动创建的。我的猜测是，我之前使用的安装包含了过时的配置细节，而且与Hadoop的安装完全不同。
