How to Resolve the '(Bucket Not Deleted) Amazon S3 Error: A Conflicting Conditional Operation Is Currently In Progress Against This Resource'
How to Resolve the “(Bucket Not Deleted) Amazon S3 Error: A Conflicting Conditional Operation Is Currently In Progress Against This Resource”
As data scientists or software engineers, we often encounter various error messages in our daily work. A common error when dealing with Amazon Simple Storage Service (S3) is “Bucket Not Deleted: A conflicting conditional operation is currently in progress against this resource”. This error is particularly noticeable when we try to delete an S3 bucket that is currently in use or undergoing other operations. In this blog post, we are going to demystify this error and provide a step-by-step guide on how to resolve it.
What Is The Amazon S3 “Bucket Not Deleted” Error?
Amazon S3 is a highly scalable, reliable, and low-latency data storage service offered by Amazon Web Services (AWS). A common operation in S3 is creating and deleting buckets, which are essentially containers for data stored in S3.
The “Bucket Not Deleted” error typically arises when there are pending operations on the bucket, such as data transfers or bucket policy changes. This error message is Amazon S3’s way of preventing data loss or corruption due to concurrent operations.
Why Does This Error Occur?
AWS ensures data integrity and consistency by restricting simultaneous conflicting operations on a bucket. If a bucket is being modified, accessed, or if there are ongoing data transfers, AWS prevents deletion to maintain data integrity.
For example, let’s say you’ve started a large file upload to your S3 bucket. While the upload is in progress, you attempt to delete the bucket. AWS will throw the “Bucket Not Deleted” error because the delete operation conflicts with the ongoing file upload.
How to Resolve This Issue?
Resolving this error involves two steps: identifying the conflicting operations and stopping them.
1. Identifying Conflicting Operations
Conflicting operations can include:
- Ongoing file transfers (uploads, downloads)
- Changes to bucket policy or permissions
- Operations by AWS services utilizing the bucket (like Amazon EMR, Amazon Redshift)
Tools like the AWS Management Console, AWS CLI, or SDKs can be used to identify these operations.
2. Stopping Conflicting Operations
Once you’ve identified the conflicting operations, you need to stop them:
- File Transfers: If there are ongoing file transfers, wait for them to complete or manually terminate them using the relevant tool or client.
- Bucket Policy or Permissions Changes: If changes to the bucket policy or permissions are in progress, wait for them to complete.
- Operations by AWS Services: If AWS services like EMR or Redshift are using the bucket, you’ll need to stop these jobs first.
The Amazon S3 “Bucket Not Deleted” error is a safety mechanism to prevent data loss or corruption. To avoid it, ensure you stop all conflicting operations before deleting a bucket.
Remember, always be cautious when deleting S3 buckets. Make sure you have backed up essential data, as the delete operation is irreversible. Happy coding!
