             Summary: Datanodes' dnlayoutversion/VERSION file containers incorrect cluster ID
                 Key: HDDS-5560
                 URL: https://issues.apache.org/jira/browse/HDDS-5560
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Ethan Rose


 **Taken from a datanode as part of a docker cluster

**Global version file at metadata/dnlayoutversion/VERSION (incorrect cluster ID):

{code}

#Fri Jul 23 17:52:54 UTC 2021
firstUpgradeActionLayoutVersion=2
cTime=1627062428170
clusterID=18539b4c-28ae-4dfb-a668-6437c2df56f6
nodeType=DATANODE
layoutVersion=2

{code}

Volume specific version file at hdds/hdds/VERSION (correct):

{code}

#Fri Jul 23 17:45:20 UTC 2021
datanodeUuid=18539b4c-28ae-4dfb-a668-6437c2df56f6
ctime=1627062320832
clusterID=CID-faab32bd-91e1-4ffc-a942-e4252d8af722
layOutVersion=1
storageID=DS-1876fa77-6c75-4b91-b724-7802a362af52

{code}

Global datanode.id file (correct):

{code}

!!org.apache.hadoop.ozone.container.common.helpers.DatanodeIdYaml$DatanodeDetailsYaml {
 certSerialId: null,
 currentVersion: 1,
 hostName: b08914e5c4ae,
 initialVersion: 1,
 ipAddress: 10.9.0.15,
 persistedOpState: IN_SERVICE,
 persistedOpStateExpiryEpochSec: 0,
 portDetails: {
 },
 uuid: 18539b4c-28ae-4dfb-a668-6437c2df56f6
}

{code}

 

All datanodes use the same cluster ID in their volume specific version files, and SCM shows a matching cluster ID. This means the value \{code}CID-faab32bd-91e1-4ffc-a942-e4252d8af722\{code} is the correct cluster ID. The other two files show the datanode UUID as \{code}18539b4c-28ae-4dfb-a668-6437c2df56f6\{code}, which is incorrectly used as the cluster ID in the global datanode version file.
