Hadoopのインストールの一部に、ssh経由でlocalhostへのパスワードなし接続が必要です。指示はかなりシンプルです。Hadoopインストール用のsshへのローカルホストへのトラブルシューティングOSX

パスワードを尋ねてきます。私は多くのことを試しましたが、できるだけ短くしていきます。
- リモートロギングは、私は完全に私の〜。/ sshのディレクトリをきれいにしてから、私は自分のコンピュータとそれらの簡単なステップにバニラのユーザーアカウントから試してみました好奇心から、キー
- を生成念の
- を有効になっていますは役に立ちました
- 以前はGitのためにsshを使って仕事をしていたリモートサーバに接続していました
- 私の知る限り、/ etc/sshはシステム全体に広がっています。私はそれを演奏する必要はありませんが、私はそれらのパラのカップルを変更しようとしましたが念のためメートル
- 私は私が600にの〜/ .ssh/authorized_keysにの許可を変更し
- 念のためにRSAおよびDSAを作成したが、バニラ、ユーザが644を持っており、それはまだだから
の作品私が試した手順をまとめてください。私はこの問題について多くの投稿があることを知っていますが、私はそれが通常の容疑者ではないと感じるようになります。たぶん私のアカウントとバニラの違いを見つけるのに役立つ正しい方向で私を指すことができます。
価値があるのは、仮想マシンを使って試してみることをお勧めします。そうすれば、1）あなたのマシンで設定が乱れるのを避けることができます。2）空白のスレートがあります。3）生産システムに移行したときの設定が一貫しています。 Mac hadoopクラスタを使用することは決してありません...また、Cloudera Quickstart VMを見つけて、Hadoopエコシステムをすぐに使い始めることができます –
