--------------------------------------
Summary: usedNamespace is being decremented incorrectly
Key: HDDS-14435
URL: https://issues.apache.org/jira/browse/HDDS-14435
Project: Apache Ozone
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Wei-Chiu Chuang
[~sarvekshayr] reported that after HDDS-13756 seems to cause a regression:
https://github.com/apache/ozone/pull/9115#discussion_r2685116012
{noformat}
After this PR, observed an issue where usedBytes is high while usedNamespace is
0, even though the bucket has no keys.
It appears that usedNamespace is being decremented incorrectly. In the
overwrite case, the namespace seems to be reduced twice, whereas it should done
once by 1.
Since the bucket has no data, this likely indicates a problem in how namespace
is being updated during the commit or delete flow.
