-------------------------------------
Yeah this can probably be moved out to 0.7.0.
> Incorrect container checksum upon downgrade

> Key: HDDS-2268
> URL: https://issues.apache.org/jira/browse/HDDS-2268
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Attila Doroszlai
> Assignee: Aravindan Vijayan
> Priority: Major
> Labels: Triaged, upgrade
>
> Container file checksum is calculated based on all YAML fields in a given
> Ozone version. If the same container file is used in older Ozone, which has
> fewer fields, the expected checksum will be different.
> Example: origin pipeline ID and origin node ID were added for HDDS-837 in
> Ozone 0.4.0. Starting Ozone 0.3.0 with the same data results in checksum
> error.
