Worked on the apache/hadoop repository to enhance NameNode locking mechanisms, focusing on concurrency control and performance evaluation. Developed and refactored core Java components to improve lock management, including moving FSNamesystemLockMode to a utility package and refining lock state checks. Introduced a benchmarking tool that measures NameNode throughput under various read/write ratios and concurrency levels, providing actionable data for performance tuning in distributed systems. Addressed locking-related bugs and updated documentation to reflect these changes, ensuring maintainability and clarity. Leveraged skills in Java, Hadoop HDFS, and benchmarking to deliver features that support scalability and reliability for large-scale cluster environments.
