Hadoop安装问题：

我按照教程安装Hadoop。不幸的是，当我运行start-all.sh脚本时，控制台上显示了以下错误：

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，抛出了以下错误

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

我是hadoop新手，所以请给我看一篇文章，这篇文章将帮助我安装hadoop而不会出现问题

或者，如果可能（更可取）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

检查

/usr/local/hadoop/logs

权限。如果不在hduser下，请更改所有权

---

sudo chown-R username:group directory

您是否尝试过

启动dfs.sh

试试下面的命令，看看有什么反应

hdfs namenode -format
start-dfs.sh
start-yarn.sh

---

老实说，我不知道我为什么会犯那样的错误。。但我按照中提供的说明拆除了我的整个装置，并使用官方网站中描述的安装方法重新安装了它-

---

但是你是对的@Krishna，日志是在安装后自动创建的。我的猜测是，我之前使用的安装的配置细节已经过时，并且很可能与Hadoop的安装有关。您当前的用户对/usr/local/Hadoop的权限有限。 尝试更改权限

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

---

请检查是否使用命令chmod或chown在文件夹上正确设置了权限

Hadoop提供单个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如何安装ApacheHadoop

我遇到了类似的问题，我发现HADOOP-env.sh中的HADOOP_前缀路径不完整。 它没有指向我的安装目录，而是指向根目录。 解决了这个问题，一切正常

正道

export HADOOP_PREFIX=/home/karan/hadoop-install/hadoop-3.2.1

走错路

export HADOOP_PREFIX=/hadoop-install/hadoop-3.2.1

我也有同样的问题

我删除了这个文件夹：

hadoop-hadoop_amine-datanode-amine.out位于：usr/local/hadoopy/logs

start-dfs.sh start-warn.sh

实际上“/usr/local/hadoop”下没有日志目录。我是否遗漏了某个配置？如果您查看hadoop-env.sh文件内部，您将找到存储日志文件的位置$默认情况下，HADOOP_HOME/logs#导出HADOOP_LOG_DIR=${HADOOP_LOG_DIR}/$USER。如果日志目录不存在，则意味着它将自动创建日志文件，但尚未创建日志文件。。我跟着教程走了。这是不是把安装搞砸了？
