Hi, All. Here is a better example.
I'll update the PR description with this.
Thank you, all.
**Target Scenario**
```scala
scala> val dsView1 = spark.range(8).repartition(8, $"id")
scala> dsView1.createOrReplaceTempView("dsView1")
scala> sql("select id from dsView1 distribute by id").explain(true)
```
**Before**
```scala
scala> sql("select id from dsView1 distribute by id").explain(true)
== Parsed Logical Plan ==
'RepartitionByExpression ['id]
+- 'Project ['id]
+- 'UnresolvedRelation `dsView1`
== Analyzed Logical Plan ==
id: bigint
RepartitionByExpression [id#0L]
+- Project [id#0L]
+- SubqueryAlias dsview1
+- RepartitionByExpression [id#0L], 8
+- Range (0, 8, splits=8)
== Optimized Logical Plan ==
RepartitionByExpression [id#0L]
+- RepartitionByExpression [id#0L], 8
+- Range (0, 8, splits=8)
== Physical Plan ==
Exchange hashpartitioning(id#0L, 200)
+- Exchange hashpartitioning(id#0L, 8)
+- *Range (0, 8, splits=8)
```
**After**
```scala
scala> sql("select id from dsView1 distribute by id").explain(true)
== Parsed Logical Plan ==
'RepartitionByExpression ['id]
+- 'Project ['id]
+- 'UnresolvedRelation `dsView1`
== Analyzed Logical Plan ==
id: bigint
RepartitionByExpression [id#0L]
+- Project [id#0L]
+- SubqueryAlias dsview1
+- RepartitionByExpression [id#0L], 8
+- Range (0, 8, splits=8)
== Optimized Logical Plan ==
RepartitionByExpression [id#0L]
+- Range (0, 8, splits=8)
== Physical Plan ==
Exchange hashpartitioning(id#0L, 200)
+- *Range (0, 8, splits=8)
```
