> Key: HDDS-5277
> URL: https://issues.apache.org/jira/browse/HDDS-5277
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Recon
> Affects Versions: 1.1.0
> Reporter: Nilotpal Nandi
> Assignee: Aravindan Vijayan
> Priority: Major
> Fix For: 1.2.0
>
>
> Decommissioned nodes have "DECOMMISSIONING" operational status in recon.
> RCA
> Recon relies on DN heartbeats to understand Node operational state. If the
> node goes down before it reports itself as DECOMMISSIONED, then there is a
> loss of information on Recon side. It is the SCM that moves a node form
> DECOMMISSIONING to DECOMMISSIONED state first, then the Datanode persists the
> state change locally, and then heartbeats with the new state to SCM & Recon
> subsequently. If the DN is shutdown before it can heartbeat the state change
> to Recon, then Recon lives with the stale information.
