Summary: Serialisation bug in Recon's listKeys API
Key: HDDS-11848
URL: https://issues.apache.org/jira/browse/HDDS-11848
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Recon
Reporter: Siddhant Sangwan
Assignee: Siddhant Sangwan
The listKeys API returns an error response when the /api/v1/keys/listKeys
endpoint on port 9888 is used.
To reproduce, create a volume, bucket, and key:
{code}
$ ozone sh key list /vol1/bucket2
[ {
"volumeName" : "vol1",
"bucketName" : "bucket2",
"name" : "key",
"owner" : "hadoop",
"dataSize" : 4068,
"creationTime" : "2024-12-03T10:04:58.063Z",
"modificationTime" : "2024-12-03T10:04:58.629Z",
"replicationConfig" : {
"replicationFactor" : "ONE",
"requiredNodes" : 1,
"minimumNodes" : 1,
"replicationType" : "RATIS"
},
"metadata" : { },
"tags" : { },
"file" : true
} ]
{code}
and call
{code}
http://localhost:9888/api/v1/keys/listKeys?startPrefix=/vol1/bucket2&limit=1000
{code}
This will return an error:
{code}
Conflicting/ambiguous property name definitions (implicit name 'key'): found
multiple explicit names: [key, isKey], but also implicit accessor: [method
org.apache.hadoop.ozone.recon.api.types.KeyEntityInfoProtoWrapper#setKey(java.lang.String)][visible=true,ignore=false,explicitName=false]
(through reference chain:
org.apache.hadoop.ozone.recon.api.types.ListKeysResponse["keys"])
{code}
KeyEntityInfoProtoWrapper has two fields, key and isKey. isKey has a
corresponding getter called isKey(). Jackson finds these three ambiguous, even
though they're annotated. The fix is to change isKey() to getIsKey().
