Das war die Aufforderung
Enter file in which to save the key (/home/dhruvhadoop1/.ssh/id_rsa)
und Sie haben nicht mit einem Dateipfad geantwortet.
Starten Sie deshalb die Generierung erneut über
su - hadoopuser
ssh-keygen -t rsa -P ""
und verwenden Sie den Standardwert oder einen anderen Dateinamen cat ..., aber keinen Befehl wie zB
/home/hadoopuser/.ssh/id_rsa.pub
Danach
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
