             Summary: Support Tracking of Deleted Files and Directories in Recon NSSummary
                 Key: HDDS-13479
                 URL: https://issues.apache.org/jira/browse/HDDS-13479
             Project: Apache Ozone
          Issue Type: Improvement
          Components: Ozone Recon
    Affects Versions: 2.0.0
            Reporter: Arafat Khan
             Fix For: 2.1.0


Steps to Reproduce:
1. Create directory structure: /dir1/dir2/f1.txt
2. Delete dir2 (Event 1: directory deletion)
3. Delete f1.txt (Event 2: file deletion)
4. Call fetchSizeForDeletedDirectory for dir2

Expected: Returns actual disk space consumed by f1.txt in deletedTable
Actual: Returns 0 because NamespaceSummary.sizeOfFiles was subtracted

Root Cause: NamespaceSummary tracks deleted files by subtracting their size, but deletedTable still contains the actual data blocks. fetchSizeForDeletedDirectory only considers NamespaceSummary data, leading to incorrect size calculations.

Impact: Incorrect space reclamation reports and misleading storage summary.
