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

             Summary: Make Literal ArrayBasedMapData string representation disambiguous
                 Key: SPARK-33292
                 URL: https://issues.apache.org/jira/browse/SPARK-33292
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.1, 2.4.7, 3.1.0
            Reporter: Dongjoon Hyun


Literal ArrayBasedMapData has inconsistent string representation from `LogicalPlan` to `Optimized Logical Plan/Physical Plan`. Also, the representation at `Optimized Logical Plan` and `Physical Plan` is ambiguous like `keys: [key1], values: [value1] AS c#0`.

{code}
scala> spark.version
res0: String = 2.4.7

scala> sql("SELECT map('key1', 'value1') c").explain(true)
== Parsed Logical Plan ==
'Project ['map(key1, value1) AS c#0]
+- OneRowRelation

== Analyzed Logical Plan ==
c: map<string,string>
Project [map(key1, value1) AS c#0]
+- OneRowRelation

== Optimized Logical Plan ==
Project [keys: [key1], values: [value1] AS c#0]
+- OneRowRelation

== Physical Plan ==
*(1) Project [keys: [key1], values: [value1] AS c#0]
+- Scan OneRowRelation[]
{code}
