During January 2026, contributed to the apache/hadoop repository by delivering a secure password handling enhancement for Hadoop data sources. This work involved refactoring both HikariDataSourceConnectionFactory and MySQLStateStoreHikariDataSourceConnectionFactory to utilize DFSUtil.getPassword, centralizing and standardizing credential retrieval. By consolidating password management logic, the update improved security, consistency, and maintainability across critical backend components. The enhancement addressed the requirements of HDFS-17873 and closed a related issue, laying the foundation for future password policy improvements. The work was implemented using Java and focused on backend development and database management, with no major bugs fixed during this period but clear depth in the feature delivered.
