UENISHI Kota created HDDS-5893:
----------------------------------
Summary: Potential data loss on multipart upload commit
Key: HDDS-5893
URL: https://issues.apache.org/jira/browse/HDDS-5893
Project: Apache Ozone
Issue Type: Bug
Components: OM
Affects Versions: 1.1.0, 1.0.0, 0.5.0
Reporter: UENISHI Kota
In case mutlipart upload completion with unused parts, and the key is first
created (no previous version), the committed live version of OmKeyInfo is added
to deletion table. The key will be live until the deletion service collects the
blocks, but after blocks deleted, the key metadata will be visible from user
API while the blocks are already deleted.
This potential bug has been resident since HDDS-2395, as long as I searched the
Git history. (I have just found this issue during the code review, so I have
not yet reproduced manually and I may miss other code.) I'll post an instant
patch later.
