PROFILE
Yaniv Kunda
Worked on apache/hadoop and apache/datafusion-comet repositories, focusing on stability and maintainability. In apache/hadoop, refactored Java test code to use try-with-resources for FSDataOutputStream, addressing resource leaks and improving test reliability. Also upgraded the ftpserver dependency to resolve Maven build issues, enhancing CI/CD consistency. In apache/datafusion-comet, upgraded Spark from version 3.5.4 to 3.5.5, updating build tools and dependency management to ensure compatibility and smooth integration. Maintained ShimCometScanExec functionality with the new Spark release, aligning configuration files and tests. Demonstrated proficiency in Java, Scala, and resource management while strengthening build health and runtime stability across both projects.

Jan 1, 2025January 2025 monthly summary: Delivered a focused resource-management improvement in Hadoop's FTP FileSystem tests by refactoring TestFTPFileSystem.java to use try-with-resources, ensuring FSDataOutputStream is properly closed and eliminating a class of resource leaks in the test suite. This work shipped alongside a dependency upgrade to ftpserver to resolve a Maven/POM issue (HADOOP-19392), as captured in commit e41f2ba15521e7a363defc8a0e4840e0c004a126. Together, these changes strengthened test reliability, reduced flaky failures, and improved build stability for the apache/hadoop repository.
