EMR Serverless - [BUG]: Updating tags on EMR Serverless Application requires app to be stopped

[mehdimld]

Name of the resource

AWS::EMRServerless::Application

Resource Name

No response

Issue Description

When using CDK to update tags on an AWS::EMRServerless::Application resource, the CloudFormation deployment fails if the application is in a STARTED state.
The error returned is:

Only MaxConcurrentRuns from SchedulerConfiguration can be updated when application is in STARTED state.

This behavior is inconsistent with both:

• The CloudFormation documentation, which states that Tags updates require No interruption

• The AWS console, which allows adding/removing tags while the application is running (STARTED state)

Expected Behavior

I expect cdk deploy (CloudFormation update) to succeed when adding/updating/removing tags on an EMR Serverless Application that is in a STARTED state

Observed Behavior

cdk deploy fails when the application is running.

CloudFormation attempts an UpdateApplication API call, which is rejected.

Deployment only succeeds if I manually STOP the application before running cdk deploy.

Sample CloudTrail event

"eventSource": "emr-serverless.amazonaws.com",
"eventName": "UpdateApplication",
"errorCode": "ValidationException",
"responseElements": {
"message": "Only MaxConcurrentRuns from SchedulerConfiguration can be updated when application is in STARTED state."
}
}

Test Cases

Minimal CDK example:

from aws_cdk import (
    App,
    Stack,
    CfnTag,
    aws_emrserverless as emrs
)
from constructs import Construct

class ReproStack(Stack):
    def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        emrs.CfnApplication(
            self, "App",
            name="repro-app",
            type="SPARK",
            architecture="X86_64",
            releaseLabel="emr-7.10.0",
            autoStartConfiguration=emrs.CfnApplication.AutoStartConfigurationProperty(enabled=True),
            autoStopConfiguration=emrs.CfnApplication.AutoStopConfigurationProperty(enabled=True, idleTimeoutMinutes=15),
            maximumCapacity=emrs.CfnApplication.MaximumAllowedResourcesProperty(cpu="10", memory="40", disk="200GB"),
            tags=[CfnTag(key="env", value="dev")]  # Change this tag and redeploy while app is STARTED -> fails
        )

app = App()
ReproStack(app, "EmrServerlessTagRepro")
app.synth()

1. Deploy stack with initial tags.
2. Start the EMR Serverless application manually (or set auto-start).
3. Change or add a tag in CDK/CFN and deploy.
4. Observe failure with ValidationException
