Setting up Amazon EMR - Amazon EMR

Setting up Amazon EMR

Complete the tasks in this section before you launch an Amazon EMR cluster for the first time:

Sign up for AWS

If you do not have an AWS account, complete the following steps to create one.

To sign up for an AWS account
  1. Open

  2. Follow the online instructions.

    Part of the sign-up procedure involves receiving a phone call and entering a verification code on the phone keypad.

    When you sign up for an AWS account, an AWS account root user is created. The root user has access to all AWS services and resources in the account. As a security best practice, assign administrative access to an administrative user, and use only the root user to perform tasks that require root user access.

Create an Amazon EC2 key pair for SSH


With Amazon EMR release versions 5.10.0 or later, you can configure Kerberos to authenticate users and SSH connections to a cluster. For more information, see Use Kerberos authentication.

To authenticate and connect to the nodes in a cluster over a secure channel using the Secure Shell (SSH) protocol, create an Amazon Elastic Compute Cloud (Amazon EC2) key pair before you launch the cluster. You can also create a cluster without a key pair. This is usually done with transient clusters that start, run steps, and then terminate automatically.

If... Then...

You already have an Amazon EC2 key pair that you want to use, or you don't need to authenticate to your cluster.

Skip this step.
You need to create a key pair. See Creating your key pair using Amazon EC2.
