             Summary: Assign a name to the error class _LEGACY_ERROR_TEMP_2003
                 Key: SPARK-42839
                 URL: https://issues.apache.org/jira/browse/SPARK-42839
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.5.0
            Reporter: Max Gekk


Choose a proper name for the error class *_LEGACY_ERROR_TEMP_2000* defined in {*}core/src/main/resources/error/error-classes.json{*}. The name should be short but complete (look at the example in error-classes.json).

Add a test which triggers the error from user code if such test still doesn't exist. Check exception fields by using {*}checkError(){*}. The last function checks valuable error fields only, and avoids dependencies from error text message. In this way, tech editors can modify error format in error-classes.json, and don't worry of Spark's internal tests. Migrate other tests that might trigger the error onto checkError().

Improve the error message format in error-classes.json if the current is not clear. Propose a solution to users how to avoid and fix such kind of errors.
