Contributed to the apache/bigtop-manager repository by delivering a high-availability deployment feature for HDFS, introducing journal nodes and zkfc to enable seamless failover and improve data reliability across Hadoop clusters. Addressed operational challenges by developing scripts for managing journal nodes and zkfc components, automating configuration and reducing manual intervention. Enhanced cluster stability by implementing multi-name-node and journal-node configuration, validated through end-to-end tests simulating failover scenarios. Additionally, resolved a reliability-critical bug affecting multi-disk storage initialization, ensuring Hadoop services could utilize multiple storage locations. Demonstrated expertise in backend development, Java, and system administration, with a focus on reliability and maintainability.

Dec 1, 2025Month: 2025-12. Concise monthly summary for the Apache BigTop Manager project focusing on reliability, scalability, and operational value. Key features delivered: - High Availability (HA) deployment for HDFS with journal nodes and zkfc. Implemented multi-name-node and journal-node configuration to enable seamless failover and improve data reliability across the cluster. - Added new scripts to manage journal nodes and zkfc components, simplifying operational tasks and reducing manual overhead. - Tests were added to validate journal nodes, zkfc functionality, and overall HA failover scenarios. Major bugs fixed: - No explicit hotfixes logged this month. The work directly addressed reliability gaps by introducing HA components, reducing single points of failure and improving failover behavior. Overall impact and accomplishments: - Increased HDFS availability and resilience for large-scale deployments, enabling safer rollouts and shorter recovery times. - Reduced admin toil through automation (scripts) and better configuration handling for HA topology. - Strengthened data reliability and cluster stability in production environments. Technologies/skills demonstrated: - HDFS high-availability architecture (JournalNode, zkfc) - Multi-name-node and journal-node configuration management - Script development for operational tasks - Test-driven validation of HA features and failover scenarios - Change management and commit tracing (commit c0d667db01a39b062668cfd86ac6b83e185825dd, message: feat: add HA deployment function for HDFS (#268))
