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

             Summary: UserDefinedType.typeName gives wrong result
                 Key: SPARK-10472
                 URL: https://issues.apache.org/jira/browse/SPARK-10472
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.4.1, 1.3.1, 1.2.2, 1.5.0
            Reporter: Cheng Lian
            Assignee: Cheng Lian
            Priority: Minor


{{DataType.typeName}} is defined as:
{code}
  /** Name of the type used in JSON serialization. */
  def typeName: String = this.getClass.getSimpleName.stripSuffix("$").dropRight(4).toLowerCase
{code}
The {{dropRight(4)}} is used to drop the {{Type}} suffix. However, UDTs may not have such suffix. For example, {{NestedStructUDT.typeName}} gives {{nestedstruc}}.
