i ran "launch-cluster" on ec2, but hadoop did not start. i would like to login as hadoop and run start-all.sh and see what error i get.
i tried ssh -i bootstrap-private-key.pem hadoop@ec2-public-ip and that failed i tried ssh -i bootstrap-private-key.pem ubuntu@ec2-public-ip which worked then i tried to switch users to hadoop: su - hadoop but it asked me for a password i do not have. i could use a suggestion.
