Github user hvanhovell commented on the issue:

https://github.com/apache/spark/pull/15072
  
@HyukjinKwon can we move this into a set specific method within Dataset 
itself, for example:
```scala
/** A convenient function to wrap a set based logical plan and produce a 
Dataset. */
@inline private def withSetPlan[U : Encoder](logicalPlan: => LogicalPlan): 
Dataset[U] = {
  if (classTag.runtimeClass == classOf[Row]) {
// Set operators widen types (change the schema), so we cannot reuse 
the row encoder.
Dataset.ofRows(sparkSession, logicalPlan).asInstanceOf[Dataset[U]]
  } else {
Dataset(sparkSession, logicalPlan)
  }
}
```

Hi @hvanhovell, What do you think about this?
Would this one be like the one we might merge if we can't find any better 
way until the next release? or it seems too hacky? I am being hesitated whether 
I should close this or not.
