找不到hadoop start-xxx.sh命令，语法错误

Question

我在MacOS上安装了Hadoop。我都尝试按照在Hadoop documentaion和Brew上发布的方法进行操作。但是，每当我尝试运行start-dfs.sh或start-yarn.sh或start-all.sh时，它只会引发以下错误：

我已经完成了Hadoop tutorial上的所有步骤。
而且我还尝试了在Stackoverflow上找到的解决方案，例如使用bash而不是sh来运行脚本并使用sudo。

我的MacOS版本是：10.14
Hadoop版本为：3.1.1

我确实看到了similar question on stackoverflow。
但是在那个帖子中没有任何可行的解决方案被回答，问这个问题的人说他已经解决了。我没有足够的声誉来评论和联系该用户masterX。

Answer 1

检查启动文件的权限。可能存在权限问题。 您是否为Hadoop作业创建了其他用户？

Answer 2

该错误可能有很多原因：

1. 这可能是由于Hadoop环境变量的配置错误所致。尝试export HADOOP_HOME=/usr/local/Cellar/hadoop/3.1.1/。
2. 可能需要权限：请尝试sudo chown YOURUSERNAME:YOURUSERNAME /usr/local/Cellar/hadoop/3.1.1/ -R。
