Este fue el mensaje
Enter file in which to save the key (/home/dhruvhadoop1/.ssh/id_rsa)
y no has respondido con una ruta de archivo.
Por lo tanto, comience la generación nuevamente a través de
su - hadoopuser
ssh-keygen -t rsa -P ""
y use el valor predeterminado u otro nombre de archivo pero no un comando como cat ...
, por ejemplo
/home/hadoopuser/.ssh/id_rsa.pub
Después
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
