推荐答案

从您的命令历史中可以看出，您可以通过 / usr替换 hadoop / local / hadoop / bin / hadoop 它应该有帮助。

As it seems from your commands history, you can replace hadoop by /usr/local/hadoop/bin/hadoop and it should help.

如果你想要使用 hadoop 命令而不指定它的完整路径，你可以编辑〜/ .bashrc 文件并添加以下行：

If you want to use hadoop command without specifying the full path to it, you can edit ~/.bashrc file and add the following line:

export PATH=$PATH:/usr/local/hadoop/bin/

然后你需要重新打开你的终端。

Then you need to reopen your terminal.
