-------------------------------------

             Summary: Use a map to store values for NamedLambdaVariable.
                 Key: SPARK-25223
                 URL: https://issues.apache.org/jira/browse/SPARK-25223
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Takuya Ueshin


Currently we use {{functionsForEval}}, {{NamedLambdaVarible}} s in which are replace with of arguments from the original functions, to make sure the lambda variables refer the same instances as of arguments, but it's pretty hacky.
Instead, we can use a global map and set/get the lambda variable values in the map.
