Min Yang developed a configurable SSL handshake timeout feature for the apache/celeborn repository, focusing on the RPC components that handle internal shuffle traffic. By introducing production-aligned timeout settings for the rpc_app and rpc_service transports, Min addressed connection timeout issues that can lead to Spark task failures. The solution leveraged Java and Scala, applying backend development and network programming skills to implement a configuration-driven approach with clear defaults. This work enhanced the reliability and tunability of Celeborn’s shuffle operations, demonstrating a deep understanding of SSL/TLS configuration and the importance of robust, production-ready transport layer design in distributed systems.
