Enter file in which to save the key (/home/dhruvhadoop1/.ssh/id_rsa)

ファイルパスを回答していません。

したがって、次の方法で再度生成を開始します。

su - hadoopuser
ssh-keygen -t rsa -P ""

デフォルト値または別のファイル名を使用しますが、次のようなコマンドは使用しませんcat ...。

/home/hadoopuser/.ssh/id_rsa.pub

その後

cat /home/hadoopuser/.ssh/id_rsa.pub | sudo tee -a /home/hadoopuser/.ssh/authorized_keys
sudo chmod 600 /home/hadoopuser/.ssh/authorized_keys/authorized_keys
