Amazon EMR managed policies - Amazon EMR
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon EMR managed policies

The easiest way to grant full access or read-only access to required Amazon EMR actions is to use the IAM managed policies for Amazon EMR. Managed policies offer the benefit of updating automatically if permission requirements change. If you use inline policies, service changes may occur that cause permission errors to appear.

Amazon EMR will be deprecating existing managed policies (v1 policies) in favor of new managed policies (v2 policies). The new managed policies have been scoped-down to align with Amazon best practices. After the existing v1 managed policies are deprecated, you will not be able to attach these policies to any new IAM roles or users. Existing roles and users that use deprecated policies can continue to use them. The v2 managed policies restrict access using tags. They allow only specified Amazon EMR actions and require cluster resources that are tagged with an EMR-specific key. We recommend that you carefully review the documentation before using the new v2 policies.

The v1 policies will be marked deprecated with a warning icon next to them in the Policies list in the IAM console. The deprecated policies will have the following characteristics:

  • They will continue to work for all currently attached users, groups, and roles. Nothing breaks.

  • They cannot be attached to new users, groups, or roles. If you detach one of the policies from a current entity, you cannot reattach it.

  • After you detach a v1 policy from all current entities, the policy will no longer be visible and can no longer be used.

The following table summarizes the changes between current policies (v1) and v2 policies.

Amazon EMR managed policy changes
Policy type Policy names Policy purpose Changes to v2 policy

IAM managed policy for full Amazon EMR access by attached user, role, or group

V1 policy (to be deprecated): AmazonElasticMapReduceFullAccess

V2 (scoped) policy name: AmazonEMRFullAccessPolicy_v2

Allows users full permissions for EMR actions. Includes iam:PassRole permissions for resources.

Policy adds a prerequisite that users must add user tags to resources before they can use this policy. See Tagging resources to use managed policies.

iam:PassRole action requires iam:PassedToService condition set to specified service. Access to Amazon EC2, Amazon S3, and other services is not allowed by default. See IAM Managed Policy for Full Access (v2 Managed Default Policy).

IAM managed policy for read-only access by attached user, role, or group

V1 policy (to be deprecated): AmazonElasticMapReduceReadOnlyAccess

V2 (scoped) policy name: AmazonEMRReadOnlyAccessPolicy_v2

Allows users read-only permissions for Amazon EMR actions.

Permissions allow only specified elasticmapreduce read-only actions. Access to Amazon S3 is access not allowed by default. See IAM Managed Policy for Read-Only Access (v2 Managed Default Policy).

Default EMR service role and attached managed policy

Role name: EMR_DefaultRole

V1 policy (to be deprecated): AmazonElasticMapReduceRole (EMR Service Role)

V2 (scoped-down) policy name: AmazonEMRServicePolicy_v2

Allows Amazon EMR to call other Amazon services on your behalf when provisioning resources and performing service-level actions. This role is required for all clusters.

The v2 service role and v2 default policy replace the deprecated role and policy. The policy adds a prerequisite that users must add user tags to resources before they can use this policy. See Tagging resources to use managed policies. See Service role for Amazon EMR (EMR role).

Service role for cluster EC2 instances (EC2 instance profile)

V1 policy (to be deprecated): EMR_EC2_DefaultRole (instance profile)

Deprecated policy name: AmazonElasticMapReduceforEC2Role

Allows applications running on an EMR cluster to access other Amazon resources, such as Amazon S3. For example, if you run Apache Spark jobs that process data from Amazon S3, the policy needs to allow access to such resources.

Both default role and default policy are on the path to deprecation. There is no replacement Amazon default managed role or policy. You need to provide a resource-based or identity-based policy. This means that, by default, applications running on an EMR cluster do not have access to Amazon S3 or other resource unless you manually add these to the policy. See Default role and managed policy.

Other EC2 service role policies

Current policy names: AmazonElasticMapReduceforAutoScalingRole, AmazonElasticMapReduceEditorsRole, AmazonEMRCleanupPolicy

Provides permissions that Amazon EMR needs to access other Amazon resources and perform actions if using auto scaling, notebooks, or to clean up EC2 resources.

No changes for v2.

Securing iam:PassRole

The Amazon EMR full-permissions default managed policies incorporate iam:PassRole security configurations, including the following:

  • iam:PassRole permissions only for specific default Amazon EMR roles.

  • iam:PassedToService conditions that allow you to use the policy with only specified Amazon services, such as and

You can view the JSON version of the AmazonEMRFullAccessPolicy_v2 and AmazonEMRServicePolicy_v2 policies in the IAM console. We recommend that you create new clusters with the v2 managed policies.

To create custom policies, we recommend that you begin with the managed policies and edit them according to your requirements.

For information about how to attach policies to a users (principals), see Working with managed policies using the Amazon Web Services Management Console in the IAM User Guide.

Tagging resources to use managed policies

AmazonEMRServicePolicy_v2 and AmazonEMRFullAccessPolicy_v2 depend on scoped-down access to resources that Amazon EMR provisions or uses. The scope down is achieved by restricting access to only those resources that have a predefined user tag associated with them. When you use either of these two policies, you must pass the predefined user tag for-use-with-amazon-emr-managed-policies = true when you provision the cluster. Amazon EMR will then automatically propagate that tag. Additionally, you must add a user tag to the resources listed in the following section. If you use the Amazon EMR console to launch your cluster, see Considerations for using the Amazon EMR console to launch clusters with v2 managed policies.

To use managed policies, pass the user tag for-use-with-amazon-emr-managed-policies = true when you provision a cluster with the CLI, SDK, or another method.

When you pass the tag, Amazon EMR propagates the tag to private subnet ENI, EC2 instance, and EBS volumes that it creates. Amazon EMR also automatically tags security groups that it creates. However, if you want Amazon EMR to launch with a certain security group, you must tag it. For resources that are not created by Amazon EMR, you must add tags to those resources. For example, you must tag Amazon EC2 subnets, EC2 security groups (if not created by Amazon EMR), and VPCs (if you want Amazon EMR to create security groups). To launch clusters with v2 managed policies in VPCs, you must tag those VPCs with the predefined user tag. See, Considerations for using the Amazon EMR console to launch clusters with v2 managed policies.

Propagated user-specified tagging

Amazon EMR tags resources that it creates using the Amazon EMR tags that you specify when creating a cluster. Amazon EMR applies tags to the resources it creates during the lifetime of the cluster.

Amazon EMR propagates user tags for the following resources:

  • Private Subnet ENI (service access elastic network interfaces)

  • EC2 Instances

  • EBS Volumes

  • EC2 Launch Template

Automatically-tagged security groups

Amazon EMR tags EC2 security groups that it creates with the tag that is required for v2 managed policies for Amazon EMR, for-use-with-amazon-emr-managed-policies, regardless of which tags you specify in the create cluster command. For a security group that was created before the introduction of v2 managed policies, Amazon EMR does not automatically tag the security group. If you want to use v2 managed policies with the default security groups that already exist in the account, you need to tag the security groups manually with for-use-with-amazon-emr-managed-policies = true.

Manually-tagged cluster resources

You must manually tag some cluster resources so that they can be accessed by Amazon EMR default roles.

  • You must manually tag EC2 security groups and EC2 subnets with the Amazon EMR managed policy tag for-use-with-amazon-emr-managed-policies.

  • You must manually tag a VPC if you want Amazon EMR to create default security groups. EMR will try to create a security group with the specific tag if the default security group doesn't already exist.

Amazon EMR automatically tags the following resources:

  • EMR-created EC2 Security Groups

You must manually tag the following resources:

  • EC2 Subnet

  • EC2 Security Groups

Optionally, you can manually tag the following resources:

  • VPC - only when you want Amazon EMR to create security groups

Considerations for using the Amazon EMR console to launch clusters with v2 managed policies

You can provision clusters with v2 managed policies using the Amazon EMR console. Here are some considerations when you use the console to launch Amazon EMR clusters.


We’ve redesigned the Amazon EMR console. The auto-tagging capability is not yet available in the new console, and the new console does not show you which resources (VPC/Subnets) need to be tagged, either. See Amazon EMR console to learn more about the differences between the old and new console experiences.

  • You do not need to pass the predefined tag. Amazon EMR automatically adds the tag and propagates it to the appropriate components.

  • For components that need to be manually tagged, the old Amazon EMR console tries to automatically tag them if you have the required permissions to tag resources. If you don’t have the permissions to tag resources or if you want to use the new console, ask your administrator to tag those resources.

  • You cannot launch clusters with v2 managed policies unless all the prerequisites are met.

  • The old Amazon EMR console shows you which resources (VPC/Subnets) need to be tagged.

Amazon managed policies for Amazon EMR

An Amazon managed policy is a standalone policy that is created and administered by Amazon. Amazon managed policies are designed to provide permissions for many common use cases so that you can start assigning permissions to users, groups, and roles.

Keep in mind that Amazon managed policies might not grant least-privilege permissions for your specific use cases because they're available for all Amazon customers to use. We recommend that you reduce permissions further by defining customer managed policies that are specific to your use cases.

You cannot change the permissions defined in Amazon managed policies. If Amazon updates the permissions defined in an Amazon managed policy, the update affects all principal identities (users, groups, and roles) that the policy is attached to. Amazon is most likely to update an Amazon managed policy when a new Amazon Web Service is launched or new API operations become available for existing services.
