<a name="emr-trusted-identity-emr-studio"></a>

This section covers how to set up and use trusted identity propagation with Amazon EMR on EC2 clusters through EMR Studio. It includes the prerequisites, identity-based authorization with open table formats, and cross-account access.

This section covers the following:
+ **Prerequisites** — Configure IAM Identity Center, Lake Formation, and the Amazon EMR security configuration.
+ **Identity-based authorization** — Query open table formats (Parquet, Iceberg, and Delta Lake) with propagated identities.
+ **Cross-account access** — Access data governed by Lake Formation in a different AWS account.
