             Summary: Check the validity of built-in function aliases
                 Key: SPARK-31372
                 URL: https://issues.apache.org/jira/browse/SPARK-31372
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: jiaan.geng


Although SPARK-30184 Implement a helper method for aliasing functions, developers always forget to using this improvement.
We need to add more powerful guarantees so that aliases outputed by built-in functions are correct.
