-----------------------------------
Summary: Namespace summary API gives wrong count of directories
and keys
Key: HDDS-13841
URL: https://issues.apache.org/jira/browse/HDDS-13841
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Recon
Reporter: Abhishek Pal
Assignee: Devesh Kumar Singh
The backend API:
{code:java}
api/v1/namespace/summary?path=<path to location> {code}
gives us wrong metadata details for the number of directories and keys.
Here is a sample command output for key list and bucket info:
{code:java}
ozone sh bucket info volume1/fso-bucket
{
"metadata" : { },
"volumeName" : "volume1",
"name" : "fso-bucket",
"storageType" : "DISK",
"versioning" : false,
"listCacheSize" : 1000,
"usedBytes" : 188743680,
"usedNamespace" : 9,
"creationTime" : "2025-10-23T14:26:43.493Z",

{code:java}

However the API returns 3 keys and 3 directories only.
