During January 2026, Bhusate contributed to the apache/spark repository by delivering two targeted SQL usability improvements. He enhanced Spark SQL’s pipe syntax to support qualified column names in the DROP operator, enabling users to drop nested fields and table-alias-qualified columns. Bhusate also implemented clearer error messaging for unsupported SQL UDF usage within lambda contexts, aligning guidance with existing Python UDF patterns to reduce user confusion. His work involved extensive testing using Scala and SQL, with a focus on robust error handling and maintainability. These changes improved the clarity and consistency of Spark SQL’s user experience without introducing new bugs.
