Siyao Meng commented on HDDS-3870:
----------------------------------
The version field is not added yet as of now:
https://github.com/apache/ozone/blob/1a796f1b54610efd86d5aba0a91e8ae4d32e4af5/hadoop-hdds/interface-client/src/main/proto/DatanodeClientProtocol.proto#L264-L267
[~erose] Do you think we need this for upgrade?
> Datanode Ratis snapshot file should be versioned.

> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Aravindan Vijayan
> Priority: Major
> Labels: upgrade
>
> The Ratis snapshot file used by the Datanode contains a serialized map of
> containerId to BCSID. To ensure that changes to this logic is
> upgrade/downgrade proof, the file needs to be versioned. We could add a
> version field to the 'Container2BCSIDMapProto' proto message that is
> serialized into the file.
