Admin Permissions For EMR Studio AWS With Examples

AWS Documentation Essential IAM Administrators' EMR Studio Permissions

AWS EMR Studio Admin Permissions

Amazon Web Services documentation describes the IAM privileges administrators need to create and manage Amazon EMR Studio installations. AWS accounts need appropriate permissions to access EMR Studio resources safely and securely. The documentation helps administrators set up IAM policies for EMR Studio management access.

Running an EMR Studio requires certain IAM permissions for critical tasks. Administrators require elasticmapreduce permissions for normal tasks, especially without IAM Identity Centre authentication. EMR Studio creation requires the “elasticmapreduce:CreateStudio” permission.

The “elasticmapreduce:DescribeStudio” permission is needed to investigate a Studio's settings or status. Administrators need the “elasticmapreduce:ListStudios” access to see all EMR Studios in their account. Deactivating a Studio requires the “elasticmapreduce:DeleteStudio” access. In addition to these EMR-specific tasks, the handbook emphasises that Studio creation requires “iam:PassRole” access. The EMR service needs this permission to assume the Studio's service role and user role to communicate with other AWS services on behalf of the user or Studio.

Importantly, the handbook states that EMR Studios using IAM Identity Centre authentication require specific rights. These additional permissions' main duties are managing Studio Session Mappings, which control how users and groups authenticated through IAM Identity Centre can access and interact with the EMR Studio and the AWS IAM Identity Centre (formerly known as AWS SSO) and related directory services.

EMR Studio in IAM Identity Centre mode requires more complex permissions and actions to restrict user and group access. Individuals or groups are assigned to Studios using permissions from many AWS services.

These include “sso:AssociateProfile”, “sso:CreateApplicationAssignment”, “sso-directory:SearchUsers”, and “sso:DescribeUser” as well as rights like “elasticmapreduce:CreateStudioSessionMapping”. Also included in the assignment operations list are organisations and iam, with permissions like “organizations:DescribeOrganization” and “iam:ListPolicies”.

To retrieve user or group assignments, permissions like “elasticmapreduce:GetStudioSessionMapping” are needed. SSO-directory actions (“sso:SearchUsers” and “sso:DescribeUser”) and sso actions (“sso:DescribeApplication”) are also needed. Users and groups assigned to an EMR Studio are listed using “elasticmapreduce:ListStudioSessionMappings”. “elasticmapreduce:UpdateStudioSessionMapping” and sso-directory and sso privileges like “sso:SearchUsers”, “sso:DescribeApplication”, and “sso:DescribeInstance” are needed to alter a user or group's session policy.

Finally, deleting a Studio user or group requires permissions from sso-directory (“SearchUsers”, “DescribeGroup”), elasticmapreduce (“DeleteStudioSessionMapping”), and sso.

The AWS documentation provides sample IAM policies for both traditional IAM authentication and IAM Identity Centre authentication to help administrators set up these permissions. These images help create distinctive policies.

Administrators should fill out policy templates with their account and resource details. The placeholder values for the AWS Region code where the Studio will be placed, the AWS account ID, the Amazon Resource Name (ARN) of the object or objects the policy statement covers, and the EMR Studio service role and user role names must be changed.

Resource descriptions for service activities are vital to documentation, notably for the IAM Identity Centre sample policy. Identity Centre and Identity Centre directory APIs do not permit naming ARNs in IAM policy statements' “Resource” section, according to the specification.

In the sample policy for IAM Identity Centre mode, the “Resource” element is set to “” for sso and sso-directory service activities, authorising these actions across all resources those services support. The policy can be applied to Studio ARNs (e.g., “arn:aws:elasticmapreduce:\region>::studio/”) or role ARNs (e.g., “arn:aws:iam:::role/\EMRStudio-Service-Role>”) to allow elasticmapreduce activities. These services can be controlled more precisely at the resource level.

After customising an IAM policy with these permissions, it must be linked to the right IAM identity. This IAM user, role, or group receives policy permissions. This final stage activates EMR Studio administration tools. The detailed permissions show how important granular access control is to AWS services like EMR Studio, especially when integrated with identity management tools like IAM Identity Centre.
