Worked on the apache/hadoop repository to enhance observability in the DataXceiver service, focusing on improving error traceability during SocketTimeoutExceptions. Developed a feature that augments error logs by including the DFSClient ID and previousOpClientName, providing richer context for diagnosing client connection issues. Leveraged Java and backend development skills to update error reporting mechanisms, aligning with reliability and incident response objectives. The changes enable faster root-cause analysis and reduced mean time to recovery by making error logs more actionable. This work addressed a key area in Hadoop’s HDFS-4277, contributing to more robust monitoring and maintainability within the distributed file system.
