That failing DNS could indicate either a problem with CentOS 6.5 AMI you are using or with the VPC DNS settings. Can you share the CentOS AMI ID? For VPC are you using AmazonProvidedDNS or a custom server?

With t2.micro the process of configuring Cloudera Manager will not be able to succeed. That instance type simply doesn't have enough memory for the main server process and all the management services. Our recommendation is to use m4.large or m4.xlarge. Also for Director itself you should use an instance like c3.large for best performance. Regarding the operation system our recommendation is to use the official releases either as community AMIs or from the AWS Marketplace: https://aws.amazon.com/marketplace/seller-profile?id=16cb8b03-256e-4dde-8f34-1b0f377efe89 (for CentOS) This documentation page contains some more instructions on how to find an AMI: http://www.cloudera.com/content/www/en-us/documentation/director/latest/topics/director_deployment_ami.html Also see Requirements and Supported Versions for additional information: http://www.cloudera.com/content/www/en-us/documentation/director/latest/topics/director_deployment_requirements.html

I want to add that we received similar reports through other channels and this seems to be a transient network failure. My recommendation is to try again.

m3.medium is definitely too small to run Cloudera Manager and all the management services. My recommendation is to try again with m4.large or m4.xlarge as the Cloudera Manager instance. That should take memory related failures out of the picture.

What instance type are you using for Cloudera Manager and for the cluster nodes? What services does the cluster run and on how many instances? One reason why that API call may fail is if Cloudera Manager runs out of memory. Are you able to access Cloudera Manager with a browser after the failure?

Does the Director instance access the internet via a NAT instance? I'm asking because if it fails to download repository metadata to perform version validation it will silently ignore the failure but at the end of the process it will still flag the version as not being found in the list of parcel repositories. Do you see any errors in the client log file (~/.cloudera-director/logs) at that time? This could also be due to availability issues with archive.cloudera.com but I'm not aware of any recent incidents.

There is no such AMI matained by Cloudera. You can install R using a custom bootstrap script that Director runs or build your own AMI with those bits pre-installed.

One suggestion is to give it a try with gp2 for the root disk volume. That may make a difference. There is no explicit way of increasing that timeout. It can be done by increasing the agent heartbeat but that has important implications on other core Cloudera Manager services and features. That timeout during FirstRun is usually a sign of poor AWS performance. We faced a similar challenge in the past in our own testing and had to find ways to use different AWS accounts to get better isolation.

Are you using c3.2xlarge for your cluster? (I see ${instances.c32c} as a reference) What's the size of the root disk partition? Are there many instances under this AWS account?

Hi Kirk - > 1. The application log doesn't reveal the aws CLI commands that are run. Is there a way to > see those commands? Either before (as a dry run feature) or after? Cloudera Director integrates with the AWS API using the Java SDK. There is no straightforward way to translate those method calls as AWS CLI commands you can run standalone. In theory you should be able to figure out how to use the AWS CLI to start similar instances by inspecting the existing ones. > 2. The nodes that get provisioned do not have anything in the /etc/hosts file. How are they resolving each other? > Typically, the hosts file configuration is critical to getting Cloudera Manager to run successfully. We expect DNS configuration to be handled outside of Cloudera Director using different mechanisms: VPC configuration to use AmazonProvidedDNS via DHCP Options Sets custom bootstrap script that Director runs to configure the hostname scripts embedded into a custom AMI that configure the proper hostname during boot and handle DNS registration Cloudera Director doesn't attempt to perform any DNS configs.
