Component/s: SQL
> Scala object can't be added to OuterScopes
> ------------------------------------------
>
> Key: SPARK-13540
> URL: https://issues.apache.org/jira/browse/SPARK-13540
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
>
> Add the following test case to {{DatasetSuite}} to reproduce this issue:
> {code}
> object OuterObject {
> case class InnerClass(a: String)
> }
> test("foo") {
> OuterScopes.addOuterScope(OuterObject)
> Seq(OuterObject.InnerClass("foo")).toDS()
> }
> {code}
> Exception thrown:
> {noformat}
> org.apache.spark.sql.AnalysisException: Unable to generate an encoder for inner class `org.apache.spark.sql.OuterObject$InnerClass` without access to the scope that this class was defined in.
> {noformat}
> The reason is that the class name added to {{OuterScope}} is the the one with {{$}} suffix (class name of the object), while the Java declaring class of {{InnerClass}} is the one without {{$}} suffix.
