Stephen O'Donnell updated HDDS-14669:
-------------------------------------
Summary: Implement a new async finalize command (was: Waiting in
finalization should not block a server thread)
> Implement a new async finalize command
> --------------------------------------
>
> Key: HDDS-14669
> URL: https://issues.apache.org/jira/browse/HDDS-14669
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> SCMUpgradeFinalizer.waitForDatanodesToFinalize() currently enters a loop with
> a sleep (mirroring the original code this replaced) while it waits for
> finalize to complete. We want to change this to avoid blocking a thread and
> instead use the DN heartbeats and a polling mechanism to wait for
> finalization to complete instead.
