[jira] [Created] (SPARK-30615) normalize the column name in AlterTable

Wenchen Fan created SPARK-30615:
-----------------------------------

             Summary: normalize the column name in AlterTable
                 Key: SPARK-30615
                 URL: https://issues.apache.org/jira/browse/SPARK-30615
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Wenchen Fan


Because of case insensitive resolution, the column name in AlterTable may match the table schema but not exactly the same. The ease DS v2 implementations, Spark should normalize the column name before passing them to v2 catalogs, so that users don't need to care about the case sensitive config.
