> Key: HDDS-13891
> URL: https://issues.apache.org/jira/browse/HDDS-13891
> Project: Apache Ozone
> Issue Type: Task
> Components: Ozone Recon
> Affects Versions: 2.0.0
> Reporter: Devesh Kumar Singh
> Assignee: Devesh Kumar Singh
> Priority: Major
> Labels: pull-request-available
>
> Implement ContainerHealthTaskV2 that uses SCM's ReplicationManager as the
> single source of truth for container health status, replacing the legacy
> approach of maintaining separate health calculations in Recon. Includes batch
> processing optimization for improved performance with large container sets.
> The current ContainerHealthTask implementation has several limitations:
> 1. Inconsistent Health Status: Recon computes container health
> independently from SCM, leading to discrepancies between Recon's view and
> SCM's authoritative state
> 2. Missing Containers: Containers known to SCM but not yet synced to Recon
> are not tracked for health issues
> 3. Performance Issues: Individual database operations for each container
> cause excessive round-trips in large deployments
> 4. Data Accuracy: No guarantee that Recon's health calculations match SCM's
> ReplicationManager decisions
