Worked on the rapid7/iceberg repository to enhance commit reliability and metadata hygiene within HadoopTableOperations. Focused on backend development using Java, the work addressed a bug where temporary metadata files could persist after commit failures if a version already existed. Implemented logic to ensure these temporary files are deleted before raising a CommitFailedException, preventing stale artifacts and maintaining a clean file system state. Added comprehensive end-to-end and unit tests to validate the cleanup process, increasing confidence in error handling and reducing the risk of metadata corruption. Demonstrated depth in distributed systems and file system operations throughout the solution.
