-------------------------------------
Summary: [snapshot] SnapshotDiff command lists unmodified file as
modified
Key: HDDS-7607
URL: https://issues.apache.org/jira/browse/HDDS-7607
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Manager
Affects Versions: HDDS-6517-Snapshot
Environment: docker-compose on HDDS-6517-Snapshot
Reporter: Jyotirmoy Sinha
SnapshotDiff command lists unmodified file as modified.
Steps :
# Create volume and bucket
# Put key key1 and take snapshot snap1
# Add new key key2 and take snapshot snap2 (key1 is unchanged)
# SnapshotDiff lists key2 as added and key1 as modified
{code:java}
bash-4.2$ ozone sh volume create vol1
bash-4.2$ ozone sh bucket create vol1/buck1
bash-4.2$ ozone sh key put vol1/buck1/key1 README.md
bash-4.2$ ozone sh snapshot create vol1/buck1 snap1
bash-4.2$ ozone sh key put vol1/buck1/key2 CONTRIBUTING.md
bash-4.2$ ozone sh snapshot create vol1/buck1 snap2
bash-4.2$ ozone sh snapshot snapshotDiff vol1/buck1 snap1 snap2
Difference between snapshot snap1 and snapshot snap2:
+ key2
M key1 {code}
The keys captured under both snapshots have same data info :
{code:java}
bash-4.2$ ozone sh key info vol1/buck1/.snapshot/snap1/key1
{
"volumeName" : "vol1",
"bucketName" : "buck1",
"name" : ".snapshot/snap1/key1",
"dataSize" : 3811,
"creationTime" : "2022-12-08T09:07:10.450Z",
"modificationTime" : "2022-12-08T09:07:12.247Z",
"replicationConfig" : {
"replicationFactor" : "THREE",
"requiredNodes" : 3,
"replicationType" : "RATIS"
},
"ozoneKeyLocations" : [ {
"containerID" : 1,
"localID" : 109611004723200001,
"length" : 3811,
"offset" : 0,
"keyOffset" : 0
} ],
"metadata" : { }
}
bash-4.2$ ozone sh key info vol1/buck1/.snapshot/snap2/key1
{
"volumeName" : "vol1",
"bucketName" : "buck1",
"name" : ".snapshot/snap2/key1",
"dataSize" : 3811,
"creationTime" : "2022-12-08T09:07:10.450Z",
"modificationTime" : "2022-12-08T09:07:12.247Z",
"replicationConfig" : {
"replicationFactor" : "THREE",
"requiredNodes" : 3,
"replicationType" : "RATIS"
},
"ozoneKeyLocations" : [ {
"containerID" : 1,
"localID" : 109611004723200001,
"length" : 3811,
"offset" : 0,
"keyOffset" : 0
} ],
"metadata" : { }
} {code}
Expected response - key1 should not be listed under modified marker for
snapshotDiff
