Parameter Information for AWS Reference Templates

This table describes the parameters in the MapR reference templates for AWS. Note that different templates can display different parameters and may present the parameters in a different order.

Parameter Do this . . .
Stack name Specify the stack name. MapR resources in AWS are grouped together as a stack that you create and delete as a single unit. The stack name cannot contain spaces.
keyName Enter the key pair that you configure in Creating a Key Pair.
IAMInstanceProfile Enter the role you created in Creating a Role for the MapR Installer.
clusterName Enter a name for the cluster.
clusterAdminPassword Enter the password you will use to log into MCS or the MapR Installer. This is the password for the UID mapr.
Note: For cloud deployments, the installer uses the Cluster Admin Password as the MySQL root password when it creates a MySQL database for certain services that require a database.
clusterAdminPasswordConfirm Enter the clusterAdminPassword again for verification.
MEP Select the MapR Ecosystem Pack version.
provisioningTemplate Select from the list of auto-provisioning templates. For more information about the templates, see Auto-Provisioning Templates. Some offerings are preconfigured for provisioning and might not display this parameter.
nodeCount Specify the number of nodes in the cluster.
amiID Specify the Amazon Machine Image (AMI) ID. Leave this field empty to use a default AMI.
sshUser Specify the ssh user with sudo privilege for the AMI you specified in amiID.
instanceType Select from the list of AWS instance types. MapR CloudFormation templates support the following instance types:
  • m4.xlarge, m4.2xlarge, m4.4xlarge, m4.10xlarge, m4.16xlarge
  • m3.xlarge, m3.2xlarge
  • c4.2xlarge, c4.4xlarge, c4.8xlarge
  • c3.2xlarge, c3.4xlarge, c3.8xlarge
  • r4.large, r4.xlarge, r4.2xlarge, r4.4xlarge, r4.8xlarge
  • r3.large, r3.xlarge, r3.2xlarge, r3.4xlarge, r3.8xlarge
  • p2.xlarge
  • g2.8xlarge
  • Local Storage Instances (Use only local disks, not EBS)
  • i3.large, i3.xlarge, i3.2xlarge, i3.4xlarge, i3.8xlarge
  • d2.xlarge, d2.2xlarge, d2.4xlarge, d2.8xlarge

For more information about instance types, see Amazon EC2 Instance Types.

useInstanceStore Set this value to true if the machine type supports instance stores (ephemeral disks) and you want to use only those disks. No EBS volumes will be attached.
Note: This field is enabled for d2.* and i3.* instance types. i3.* uses NVMe disks, which are added by default in AWS. If you use i3.* images, the option is implicitly true.
diskCount Specify the disks per node.
diskType Specify the disk type. For more information, see Amazon EBS Volume Types.
diskSize Specify the disk size.
installerOnItsOwn Select true to configure the MapR Installer on a node that is not part of the cluster. When you select true, the installer is started on a t2.small instance. Select false to configure the installer on a node in the cluster. Note that if you select true, the cluster will consist of the nodeCount plus another node for the installer.
useExistingSubnet Specify a subnet ID if you want to use an existing subnet. Leave this field empty if you would like a new BPC and subnets created. If you choose to use your own subnet:
  • The subnet must have access to the Internet. Hosts on that subnet must have transparent outbound access to the Internet with no additional configuration required. This means either an automatic VPN or public IP addresses. The system will connect to the Internet to update packages and software.
  • The subnet must be able to communicate to all hosts within the subnet on all ports.
  • You must have a mechanism to connect with the hosts on the subnet.
securityGroups Specify the security group IDs for an existing subnet if you specified a subnet ID for useExistingSubnet. Leave this field empty to create a new VPC and subnets.
installOpenVPN Select True if you want to install OpenVPN. For more information, see Using OpenVPN.
openVPNuser Specify a user name for OpenVPN if you will use OpenVPN to connect to the cluster. For more information, see Using OpenVPN.
openVPNpassword Specify a password for OpenVPN if you will use OpenVPN to connect to the cluster. For more information, see Using OpenVPN
assignPublicIP If you want to assign a public IP address to each node, set this value to true. If you set the value to false, you must ensure that you have a way to connect to the private IP addresses.
Note: It is recommended that you enable assignPublicIP if you are not using your own subnet, and you are letting the template create the VPC and subnet.
publicAccess CIDR If you want to restrict the IP address from which the stack can be accessed, specify the IP address range in this field. This field applies only when the template creates the VPC and subnets.
