/etc/hosts 127.0.0.1 nagarjuna 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
and all configuration files pointing to nagarjuuna and not localhost. Gave me the above error 127.0.0.1 localhost 127.0.0.1 nagarjuna 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost and all configuration files pointing to localhost and not nagarjuna, I am able to successsfully start the cluster. Does it have something to do with password less ssh ?
