Soumitra Sulav created HDDS-6924:
------------------------------------
Summary: OBJECT_STORE isn't flat namespaced
Key: HDDS-6924
URL: https://issues.apache.org/jira/browse/HDDS-6924
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Manager
Affects Versions: 1.3.0
Reporter: Soumitra Sulav
Fix For: 1.3.0
As per the design, the OBJECT_STORE bucket layout should be flat namespaced.
But while trying to create a single key in the OBJECT_STORE, there was more
than 1 entry added to the key list.
And many of the KEYS seem invalid.
