Hi Dominika. Your blog is excellent and was extremely useful thank you. While I was digging around trying to solve this issue I did find a great description of the issues you might come across while creating the controller and clusters. It is worth adding a link to this excellent article in your blog. http://hortonworks.github.io/hdp-aws/trouble/ Regards Sharon ... View more

Hi Graham I have just created 2 instances in the same VPC as the HDC cluster I am trying to create using my key-pair with identical security groups: 1) a standard AWS micro instance and I could ssh as ec2-user to that instance fine. 2) an instance using the "Launch more software" in the Hortonworks Data Cloud - HDP services AMI. I could ssh as cloudbreak user (as per Hortonworks instruction) with my key-pair. I realise 2) is not how to commission hardware for HDC but I wanted to see if there was a difference with ssh as you suggested. From the instance overview the security groups look identical as do the inbound rules so I think the key-pair is good. Regards Sharon ... View more

Hi Graham Thanks for getting back to me so quickly. I did try with and without spot pricing enabled and there were no differences I did include the Ambari password on the form I think it gets removed from the json for security purposes. I am the administrator of our AWS resources and created the controller earlier this morning so I don't think that is an issue. Do you know what checks are carried out in order for the buttons to be activated? Perhaps I can dig into these more. Regards Sharon ... View more
