             Summary: Reuse bucket metadata after owner verification in S3 DeleteBucketLifecycle
                 Key: HDDS-16650
                 URL: https://issues.apache.org/jira/browse/HDDS-16650
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Huang Kuan Hao
            Assignee: Huang Kuan Hao


When a request includes a non-empty x-amz-expected-bucket-owner header, BucketLifecycleHandler retrieves the bucket to verify its owner. After verification succeeds, deleteLifecycleConfiguration retrieves the same bucket again before deleting the lifecycle configuration. Reuse the OzoneBucket obtained during owner verification to perform the deletion. Retain the existing lookup when the header is absent or empty. This saves one bucket metadata lookup for requests that pass expected-owner verification, while preserving the existing bucket READ requirement, owner validation, OM authorization, and error translation.

  Regression tests should verify:
  * One bucket metadata lookup with absent, empty, or matching expected-owner headers.
  * Owner mismatch and lookup failures still prevent deletion with the existing error responses.
  * Successful deletion and deletion of a missing lifecycle configuration still return HTTP 204.
  * Other OM errors retain their existing translation.
