> SCM should not close Ratis pipelines on Finalize
> ------------------------------------------------

> Key: HDDS-14646
> URL: https://issues.apache.org/jira/browse/HDDS-14646
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
>
> When SCM finalizes an upgrade, it should no longer close all the Ratis
> pipelines on the datanodes. Instead they should be kept open. The SCM
> finalize command now needs to wait for all healthy datanodes to report
> matching SLV and MLV versions to know they have been finalized. Only when all
> datanodes are finalized, should SCM complete the finalization process.
> This change is mostly to remove the existing close pipeline code and anything
> else that depended on it. The only new code added is the change to wait in
> DNs reporting SVL == MVL, as before new pipelines being created was the
> trigger to complete the process.
