我只是下载并安装hadoop，请参见下面的终端输出：

steven81@steven81-HP:/usr/local/hadoop-3.0.3/bin$ hadoop
hadoop: command not found
那为什么我会收到指示未找到hadoop命令的错误？
我该如何解决？
答案 0 :(得分：0)
您需要编辑PATH变量以在其中包含bin目录
否则，必须从该目录完全像erl_crash_dump:0.5

那样运行命令
一些示例将显示Failed: context.getThemeContext is not a function
TypeError: context.getThemeContext is not a function
at ComponentWithContext.getChildContext
，它作为绝对路径转换为./hadoop
