Pepperdata provides automated infrastructure optimization, improved management of AWS autoscaling, full-stack observability, and real-time insights—all in one place. With Pepperdata, you can save money, optimize big data performance, and run EMR applications more efficiently.

We’ll take you through the following steps to get you up and running with Pepperdata:

Getting Started

Visit the Pepperdata AWS Marketplace storefront here. You can choose a 30-day Free Trial, or if you’re ready to fully engage with Pepperdata, choose the Starter Pack to access our complete suite of features and functionality.

Click Continue to Subscribe at the top of the page, and fill out the information we need to create your Pepperdata account. We’ll need your 12-digit AWS account ID so we can link your AWS and Pepperdata accounts. You’ll find this under the My Account dropdown in your AWS account.

Once you submit your signup page, we’ll send you a few important emails you’ll need for the remaining setup steps.

Look for the email titled Your Pepperdata Trial Essentials. Inside your Pepperdata Trial Essentials email are a few important steps to configure your EMR cluster.

Task 1: Launch the CloudFormation stack to create the Pepperdata Role and grant Pepperdata access

An IAM role is required to enable Pepperdata access for operation in the EMR environment. You can create the policies for access to all resources or to only specific resources, such as clusters where given functionality is required. For details about IAM service roles and permissions, refer to the Customize IAM Roles page from Amazon.

Click the Launch Stack button in Task 1 of your Pepperdata Trial Essentials to automatically launch the CloudFormation stack to create the Pepperdata Role and grant it access. Click through the four steps of the Cloud Formation Template as shown below. You don’t need to edit anything on these pages.

At the bottom of the final step, check the acknowledgment box, then clickCreate Stack.

Task 2: Create a new cluster with Pepperdata

Now start up a new EMR cluster as usual. The procedure below assumes that you will not need to leverage any custom cluster management functions, such as certificate management. If such additional (non-Pepperdata) functions are needed, you should create a “helper bootstrap” script to invoke those functions and call the Pepperdata bootstrap script. In this case, upload the helper bootstrap script to the cluster configuration folder, and use its location and filename for the Script location field in the procedure.

Heads up! Some important items that you must pay attention to as you create your new EMR cluster:

— Be sure to choose EMR Managed Autoscaling.
Be sure to choose the IAM role created in Step 1 above.
Ensure that Security-Enhanced Linux (SELinux) is disabled. By default, EMR disables SELinux. But if it’s been enabled, you must disable it before activating Pepperdata.

Procedure

Note: These steps do not tell you how to configure everything in your cluster, only the key items needed for Pepperdata to work correctly.

1. In your Amazon AWS environment, launch the Create cluster wizard, and click Go to advanced options (not quick options).
2. Under Software and Steps > Software Configuration, be sure to choose EMR 6.1 or 6.2. If you are using an earlier version of EMR, please contact us at support.pepperdata.com for alternate instructions.

3. Under Hardware > Cluster scaling, check Enable Cluster Scaling and ensure Use EMR-managed scaling is selected.

4. Under General Cluster Settings > Additional Options, add a Bootstrap Action, and select Custom Action, then Configure and Add. Enter your custom bootstrap script location and your custom bootstrap optional arguments from your Pepperdata Trial Essentials email, as shown here:

5. Click Add to add the bootstrap script.
6. Under Security > Permissions, choose Custom Permissions. Assign the IAM role for Pepperdata access—which you already created above under Task 1: Launch the CloudFormation stack to create the Pepperdata Role and grant Pepperdata access—to the EC2 instance profile. Navigate to the Task 4: Security > Permissions section, and select Custom. In the EC2 instance profile list, select the IAM role that you previously created; it’s called PepperdataManagedAutoscalingRole.
7. Click Create Cluster.
8. Wait a few minutes while the cluster is created, the Pepperdata software is installed, and the Pepperdata services are automatically started.

Once your new EMR cluster is up and running, you can start running some jobs on your EMR cluster. You may discover you already have a simple default job or two provided by AWS.

Task 3: Reset Your Password

Approximately 30 minutes after your cluster is up and running, you should be able to login to your Pepperdata dashboard. Click the dashboard login link that is also in your Pepperdata Trial Essentials email. If asked to enter an email address, use the same one you provided in Task 2 above. Choose a secure password that meets the requirements shown.

Task 4: Visit Your Pepperdata Dashboard and Start Optimizing!

Once you log in, you should start seeing your first reports! You can always return to your Pepperdata dashboard at dashboard.pepperdata.com.
