PROFILE

Dominik Burdzy

Worked on the google/dwh-migration-tools repository to enhance observability, reliability, and compliance for Cloudera migrations. Delivered features such as dynamic resource usage collection, Spark YARN application caching, and automatic Spark History Server discovery via Knox, enabling faster diagnostics and improved data retrieval. Expanded cluster telemetry to include RAM and CPU metrics, refined Spark YARN metadata extraction, and improved application type detection by parsing system properties. Refactored authentication to support multiple methods and implemented cluster existence validation to reduce misconfigurations. Addressed license compliance and maintained backward compatibility during output file transitions, using Java, Apache Spark, and REST APIs throughout development.

February 2026 — google/dwh-migration-tools: Notable progress across metrics, Spark metadata, and compliance. Delivered expanded resource telemetry for Cloudera clusters, enabling total_physical_memory_used_across_hosts, total_physical_memory_total_across_hosts, cpu_user_rate, and cpu_system_rate across hosts to improve observability and capacity planning. Implemented Spark YARN metadata extraction and refined application type detection, including support for custom Spark history server names and improved detection by reading the Spark Java command from system properties. Completed license compliance updates ahead of release and maintained backward compatibility for resource allocation output files during the transition to new naming conventions. These changes increase reliability, traceability, and release readiness while enabling deeper insights into resource usage and Spark workloads.

January 2026: Delivered significant enhancements to the google/dwh-migration-tools project focusing on observability, reliability, and security. Implemented dynamic resource usage collection for Cloudera services, caching of Spark YARN applications, and automatic Spark History Server discovery via Knox, improving data retrieval latency and end-to-end visibility. Added cluster existence validation and authentication refactoring to support multiple methods, reducing failed tasks and tightening security. These changes establish a stronger foundation for scalable migrations and easier troubleshooting, with measurable business value in faster issue diagnosis, more reliable job execution, and improved security posture.
