Apache Spark reassigned SPARK-34395:

    Assignee: Apache Spark

> Clean up unused code for code simplifications
> ---------------------------------------------
>
>                 Key: SPARK-34395
>                 URL: https://issues.apache.org/jira/browse/SPARK-34395
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.0, 3.2.0
>            Reporter: yikf
>            Assignee: Apache Spark
>            Priority: Minor
>
> Currently, we pass the default value `EmptyRow` to method `checkEvaluation` in the StringExpressionsSuite, but the default value of the 'checkEvaluation' method parameter is the `emptyRow`.
> We can clean the parameter for Code Simplifications.
>  
> example:
> *before:*
> {code:java}
> def testConcat(inputs: String*): Unit = {
>   val expected = if (inputs.contains(null)) null else inputs.mkString
>   checkEvaluation(Concat(inputs.map(Literal.create(_, StringType))), expected, EmptyRow)
> }{code}
> *after:*
> {code:java}
> def testConcat(inputs: String*): Unit = {
>   val expected = if (inputs.contains(null)) null else inputs.mkString
>   checkEvaluation(Concat(inputs.map(Literal.create(_, StringType))), expected)
> }{code}
