Worked on the apache/spark repository to enhance Spark SQL error handling by improving the clarity of missing table exception messages. Delivered a feature that ensures error messages now include the fully qualified table name, including the catalog, when a table is not found, directly addressing debugging challenges outlined in SPARK-53558. This change streamlines the debugging process and reduces support queries by making error contexts more explicit for users. The work involved careful modification of Java and Scala code, with attention to exception message design, SQL logic, and unit testing to ensure reliability and maintainability within the Spark SQL codebase.
