> Replace _FUNC_ in UDF ExpressionInfo
> ------------------------------------
>
> Key: SPARK-28581
> URL: https://issues.apache.org/jira/browse/SPARK-28581
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Yuming Wang
> Assignee: Yuming Wang
> Priority: Major
>
> This issue aims to move {{replaceFunctionName(usage: String, functionName:
> String)}} from {{DescribeFunctionCommand}} to {{ExpressionInfo}} in order to
> make {{ExpressionInfo}} returns actual name instead of placeholder. We can
> get {{ExpressionInfo}}s directly through
> {{SessionCatalog.lookupFunctionInfo}} API and get the real names.
