> Assign a name to the error class _LEGACY_ERROR_TEMP_2004
> --------------------------------------------------------
>
> Key: SPARK-42840
> URL: https://issues.apache.org/jira/browse/SPARK-42840
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.5.0
> Reporter: Max Gekk
> Priority: Minor
> Labels: starter
>
> Choose a proper name for the error class *_LEGACY_ERROR_TEMP_2004* 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().
> If you cannot reproduce the error from user space (using SQL query), replace
> the error by an internal error, see {*}SparkException.internalError(){*}.
> 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.
