Hadoop start-all.sh error:No such file or directory
提问by Yili Jiang
After I successfully created the name node, I ran into this problem when trying to start name node. For me it seems as if it's trying to log to a file that does not exist. How could I change my setup to direct the script log to the correct directory?
成功创建名称节点后，尝试启动名称节点时遇到了这个问题。对我来说，它似乎试图登录到一个不存在的文件。如何更改我的设置以将脚本日志定向到正确的目录？

Try to run which hadoop. If this command gives you an output then your HADOOP_HOME has been set in .bashrc file.
尝试运行which hadoop。如果此命令为您提供输出，则您的 HADOOP_HOME 已在 .bashrc 文件中设置。
If not set then edit .bashrc file in your home directory and add below statements considering your hadoop is installed in /opt/hadoop. It may be another location.
如果未设置，则在您的主目录中编辑 .bashrc 文件并考虑您的 hadoop 安装在 .bashrc 中添加以下语句/opt/hadoop。它可能是另一个位置。
HADOOP_HOME=/opt/HADOOP
export HADOOP_HOME
PATH=$PATH:$HADOOP_HOME/bin
export PATH
This will help you.
这会帮助你。
