I am trying to set up a spark cluster on multiple servers using VMWare to configure them. However I have not been given root privileges for the servers. (I understand it should be possible to set up a spark cluster without root access) When I try to launch spark using sbin/start-all.sh it requests a root password to start the slave. I have already tried generating ssh keys and copying them to the servers, using the method explained in this post, however, it still request root password when I attempt to launch slave. Does anyone know a workaround this?

  • I have tried that as well. I can ssh into the servers without a password which means the ssh keys should be configured correctly. However, when I launch spark, it still requests root@user password.. – msharky Jul 20 '17 at 08:52
  • Can you also ssh as root@machine without a password? Or just as the currently logged in user? – Rick Moritz Jul 20 '17 at 11:12
