Template error creating HDP-Cloud Controller Service on AWS

[#1]

Please see the attached two documents for details:

Document 1: Create Failed-Stack Detail.pdf... contains the error details

Document 2: Create Failed-Procedure-I-Used.pdf ... contains the procedure I followed.

Please advise on how to move forward as I have not been able to create a cluster using the new HDP Cloud on AWS.

@Marton Sereg Do you know why this error happens? The error is:

CREATE_FAILED

AWS::CloudFormation::WaitCondition InstanceWaitCondition

WaitCondition received failed message: 'ERROR: command 'hdc create­credential ­­ credential­name aws­access ­­role­arn $CREDENTIAL_ROLE_ARN ­­ssh­key­url http://169.254.169.254/latest/meta­data/public­keys/0/openssh­key ­­existing­ssh­key­pair $KEYPAIR_NAME' exited with status: 1 line: 1' for uniqueId: cbd­init

We don't have it documented in the Troubleshooting documentation at http://hortonworks.github.io/hdp-aws/trouble/index.html

[#3]

I don't know why this error occurred: I am seeking advise on resolving it. Can you please help?

@Joginder Sethi

can you SSH to the control plane VM and send me the logs from:

- /var/log/cbd-quick-start.log

- the output of the "docker logs cbreak_cloudbreak_1" command

I've seen this error message once when the SSH public key that was selected on the CFN create stack page had a length shorter than 2048. Please check if your public key's length is at least 2048 because only those are supported by HDC.

[#5]

I am unable to Putty into the vpc. The .pem file is 2kb while when I generate .ppk files: the private key is 2kb but the public key is 1kb. When generate another pair of keys using AWS' "Create Key Pair" I don'r see an option to set the size of the keys.

Please advise.

What Marton meant is, SSH to the EC2 instance on which the cloud controller is running, and get the output of the logs.

To determine your SSH public key length, you could use this command ssh-keygen -lf /etc/ssh/rsa_key.pub replacing rsa_key.pub with your public key name.

If you have already generated a new kaypair, you could just try and create a new cloud controller using the new SSH keypair.

By the way, if you run into any further issues, let us know which version of HDCloud you are using. I assume 1.8? Or the technical preview?

[#8]

I am using 1.8 version of HDCloud. I have terminated ec2 instance base on your recommendation to try with newly generated key pairs.

Will report soon.

Great. Let us know how it goes. If you generated a new SSH key, it should be a 2048-bit RSA key that meets the requirements. If the cloud controller still fails, then something else causes the problem.

[#10]

Same error after using the new key. I believe the problem is the key pair as I am still not able to Putty into the ec2 instance using the public dns name or the ip. Is there another way to ssh from windows os?
