HDP3.1 Demo AMI login and introduction

[#1]

I launched an instance from this AMI in AWS:

HDP 3.1.0 with Hortoniabank demo including GDPR scenarios plus Knox SSO/NiFi v6 -1/11/2019 - ami-0b705846bc9b97e11

How to access/login to the instance?

I tried to access Ambari as following but failed:

http://<IP>:8080

https://<IP>:8443

Any introduction documents regarding how to explore this demo AMI?

Thanks.

Find document at:

After I edited C:\Windows\System32\drivers\etc\hosts with "my_IP demo.hortonworks.com"

Now I can get to login page. But after I entered admin/BadPass#1, I get back to login page again.

Still looking into this. If anyone has any idea, please let me know.

Thanks.
