As part of my evaluation I am currently running a 3 node cluster running DSE 3.0.1. I now want to add a fourth node to my cluster. I have tried to add the node via the 'Add Node' option and picking 'Cloud' as I am launching this within AWS I put in the require information I add the node as a 'Hadoop' node. I have already created a security group and using an already created keypair. I am also using the 'ami-814ec2e8' AMI to create the node. I have tried this process 3 different times on 3 different availability zones and get the error below.
Error: Installation staged failed: Installation failed on node 'IP Address': The installed agent doesn't seems to be responding'
