別のユーザーを作成する - hduser、常に推奨

- do chown -R 755 /usr/local/hadoop
- when creating tmp paths like /app/hadoop/tmp, apply the same settings as above

うまくいけば、これで問題が解決します。

問題は、hadoop ではなく許可に関連しています

以下に、非常に役立つ 2 つの提案を示します。

  1. .bashrc ファイルに HADOOP_HOME と JAVA_HOME が設定されているか確認するとよいでしょう。これらの環境変数を設定しないと、hadoop クラスターの起動中にエラーが発生する場合があります。

  2. /usr/local/hadoop/logs ディレクトリに生成されたログ ファイルを調べて、エラーをデバッグすることも役立ちます。
