Hi @Abhinandan Gupta
Based on the error message FailedToDeletePerClusterContainerErrorCode and the associated CLI output, it appears that the deletion process for your HDInsight cluster is encountering issues due to problems with the per-cluster default storage container. The issue arises when the cluster's associated storage container cannot be deleted automatically, causing the deletion process to fail.

To resolve HDInsight cluster deletion issues, navigate to the associated Azure Storage account used as the cluster's default storage. Identify and manually delete the container, which is often named after the. If deletion fails, check your IAM permissions to ensure that you or the system-assigned managed identity has the "Storage Blob Data Contributor" role. Additionally, verify if there are any resource locks applied to the storage account, and ensure that soft delete or immutability policies are not preventing deletion. Disable these settings temporarily if needed to allow the container to be removed.

After removing the storage container try to delete HDInsight cluster in AZURE portal

Please refer the below Microsoft threads and Documentation for to delete HDInsight cluster

Hey @J N S S Kasyap ,

I have already deleted the container which gets created by default. Now there are no containers in my storage account.

@Abhinandan Gupta

Use Azure CLI to Force Delete the HDInsight Cluster, This command should bypasses any failed attempts to delete the container:

az hdinsight delete \ --name <your-cluster-name> \ --resource-group <your-resource-group-name> \ --yes

https://learn.microsoft.com/en-us/cli/azure/hdinsight?view=azure-cli-latest#az-hdinsight-delete

Sometimes ARM gets stuck delete directly using the full resource ID:

az resource delete \ --ids /subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.HDInsight/clusters/<cluster-name>

https://learn.microsoft.com/en-us/cli/azure/resource?view=azure-cli-latest#az-resource-delete

If the issue persists, I will be happy to assist you further.

Thank you for confirming that you've already deleted the associated storage container and attempted both the standard and direct resource ID deletion methods using Azure CLI. Given that you're still encountering the error:

ErrorCode: FailedToDeletePerClusterContainerErrorCode; ErrorDescription: Internal server error occurred while processing the request. Please retry the request or contact support.

It strongly suggests an internal issue within the HDInsight platform that is preventing the resource from being properly cleaned up - even though the associated container is already removed.

Here are few recommended steps that might help you:

Check for Resource Locks:

Go to the Resource Group in the Azure Portal.

Check the "Locks" section to see if any Delete or ReadOnly locks exist. Remove them if present.

Verify Role Assignments:

Ensure your user or service principal has Owner or Contributor permissions at the Resource Group level.

Specifically,make sure there is no missing Microsoft.HDInsight/* permission that might block operations.

Use Azure REST API for Hard Delete (Optional)

If the Azure CLI fails, you can also try using the Resources - Delete - REST API (Azure Resource Management) | Microsoft Learn for deleting the resource directly, as this sometimes bypasses client-side SDK limitations.

Please refer the below Microsoft documentation for more information
https://learn.microsoft.com/en-us/rest/api/resources/resources/delete?view=rest-resources-2021-04-01
https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/lock-resources?tabs=json

Hi,

So I dont have any resource locks, and I have Owner permissions on the cluster as well.

@Abhinandan Gupta
Did you try Hard DELETE option via RESTAPI ?

DELETE https://management.azure.com/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.HDInsight/clusters/<cluster-name>?api-version=2021-06-01

https://learn.microsoft.com/en-us/rest/api/resources/resources/delete?view=rest-resources-2021-04-01If the REST API also fails, you're at the point where Microsoft needs to clean up the stale cluster metadata in their backend.
I will check internally to help you further on this task.

I tried using the hard delete using API with the following params:

It gave a 202 response, but the Deletion doesn't go through.

@Abhinandan Gupta
I am reaching out to internal team resolve this issue, meanwhile please check the below questions?
1.Are there any linked or dependent resources still attached to the cluster (e.g., Managed Identity, VNet, NSG, Private Endpoints, Key Vault)?

2.Are there any soft delete, immutability policies, or Azure Policy restrictions applied to the associated storage account or other related resources?
3.Are there any custom RBAC roles or deny assignments affecting the deletion permissions?
4.Have you tried deleting the cluster from a different region or Azure CLI version?

Hi,

I have raised a support ticket and they said that the product team would have to delete the cluster manually.

Hello @ Abhinandan Gupta,
Can you try the below and check if it helps you
To delete the resources and the resource group, you can try using the Azure Resource Explorer portal, as there might be underlying dependencies preventing the deletion.

Here's how you can do it:

Open the Resource Explorer portal.

Navigate to your Subscription.

Expand the Resource groups section.

Select the specific Resource Group you want to delete.

From there, manually attempt to delete the individual resources.
