PROFILE
Jinglun
Jinglun developed and integrated the VolcanoEngine Cloud TOS File System within the apache/hadoop repository, enabling Hadoop to natively interact with VolcanoEngine’s TOS object storage. Using Java and leveraging Hadoop’s FileSystem API, Jinglun introduced new components such as RawFS and RawFileSystem, along with supporting utilities, to facilitate seamless storage operations and lay the groundwork for multi-cloud support. To ensure reliability and maintainability, Jinglun delivered a comprehensive unit test suite covering core behaviors like checksum verification and URI handling. The work focused on robust API integration, cloud storage interoperability, and adherence to Apache Software Foundation standards for licensing and testing.
