After i used the ip address and the port number following the hortonworks tutorial which brought me to hortonworks site i am not able to login into ambari using admin and admin as both username and password.
Couple of things to check
1. Can you check if your iptables are running ? if so stop by running the command "service iptables stop"
2. is service is listening on 8080 port? check by running "nestat -anlp | grep 8080"
3. check /var/log/ambari-server/ambari-server.log for error messages
You can log into ambari as maria_dev with password maria_dev. Much of what you will do in the tutorials will use this login. The admin password has to be set by logging in to the shell as root and running /usr/sbin/ambari-admin-password-reset. You should have set the root password or key when you created the VM in azure.
