> Key: HDDS-13859
> URL: https://issues.apache.org/jira/browse/HDDS-13859
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Swaminathan Balachandran

>
> OmSnapshotLocalDataManager should update needsDefrag flag in the yaml file
> based on the operations performed on the SnapshotLocalDataYaml.
> Needs Defrag flag needs to be set when the snapshotLocalDataYaml was not
> present in the localDataManager before i.e. this is a newly created snapshot.
> The flag also needs to be set when the previousSnapshotId in the yaml file is
> updated which means there was a chain update inturn meaning the snapshot
> needs to be defragged.
> The flag should be reset when a new version is added and a new version would
> be only added when a snapshot is defragged thus the flag should be reset.
> To check whether a snapshot should be defragged either the flag should be set
> or the latest version of the previous snapshot is greater than the previous
> version the current snapshot's version is pointing to in the graph.
