I was trying to setup an EC2 instance to practice Hortonworks practical exam. I followed the steps mentioned in the guide. I am at step 13, where it mentioned that, I should download VNC client to connect to EC2 instance. I used public dns followed by :5901 and I am getting timeout error. Looks like it's not able to reach EC2 instance.
Please let me know if any one faced the same issue.
Something must have failed during the creation of your EC2 instance. The only thing you can do at this point is to terminate the instance and launch a new one. Make sure when you create the instance that you define the proper security group and open the right ports.
If your new instance has the same issue, please let me know.
