I started a AWS instance using the public hortonworks ami (ami-02ae336a). I am able to SSH to the instance using the ec2-user but I can't SU to root to navigate to the tutorial directory. Also when I bring up ambari, the sandbox id/password combinations don't work. Any suggestions?
The process is normally:
- SSH onto node as ec2-user, as you have
- "sudo su -" to get into root. Using the same password you ssh-ed into ec2-user.
- Once in root - "ambari-admin-password-reset" to reset the Ambari admin user.
I've not built a cluster on this exact AMI. The only other suggestion would be to try the root/hadoop combo as per the sandbox.
That AMI is not owned or maintained by Hortonworks. Also it appears this AMI was created in 2014 so is very dated:
