# How Amazon EMR uses Secrets Manager
Amazon EMR

Amazon EMR is a platform that simplifies running big data frameworks, such as Apache Hadoop and Apache Spark, on AWS to process and analyze vast amounts of data. When you use these frameworks and related open-source projects such as Apache Hive and Apache Pig, you can process data for analytics and business intelligence workloads. You can also use Amazon EMR to transform and move large amounts of data into and out of other AWS data stores and databases, such as Amazon S3 and Amazon DynamoDB. 

## How Amazon EMR running on Amazon EC2 uses Secrets Manager
EMR on EC2

When you create a cluster in Amazon EMR, you can provide application configuration data to the cluster with a secret in Secrets Manager. For more information, see [Store sensitive configuration data in Secrets Manager](https://docs.aws.amazon.com/emr/latest/ReleaseGuide/storing-sensitive-data.html) in the *Amazon EMR Management Guide*.

In addition, when you create an EMR Notebook, you can store your private Git-based registry credentials using Secrets Manager. For more information, see [Add a Git-based Repository to Amazon EMR](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-git-repo-add.html) in the *Amazon EMR Management Guide*.

## How EMR Serverless uses Secrets Manager
EMR Serverless

EMR Serverless provides a serverless runtime environment to simplify the operation of analytics applications so that you don’t have to configure, optimize, secure, or operate clusters.

You can store your data in AWS Secrets Manager and then use the secret ID in your EMR Serverless configurations. This way, you don't pass sensitive configuration data in plain text and expose it to external APIs.

For more information, see [Secrets Manager for data protection with EMR Serverless](https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/secrets-manager.html) in the *Amazon EMR Serverless User Guide*.
