Worked on the apache/ozone repository to enhance resilience and operational efficiency in Kubernetes environments by implementing DNS refresh logic and improving client failover handling. Focused on backend development using Java, the work introduced mechanisms for dynamic DNS-based refreshes to address connection failures and IP changes between Ozone clients, the Object Manager, and the Storage Container Manager. The approach included refining network programming logic and updating configuration keys to ensure smoother failover and reduced downtime. Post-commit adjustments were made to further stabilize these features, with an emphasis on distributed systems principles and robust unit testing to maintain reliability in production deployments.
