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

             Summary: UDT not working
                 Key: SPARK-7701
                 URL: https://issues.apache.org/jira/browse/SPARK-7701
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.3.1, 1.3.0
            Reporter: bogdan baraila


Using a User Define Type fails with the next exception: 

ExamplePointUDT cannot be cast to org.apache.spark.sql.types.StructType
java.lang.ClassCastException: 
ExamplePointUDT cannot be cast to org.apache.spark.sql.types.StructType
	at org.apache.spark.sql.SQLContext.createDataFrame(SQLContext.scala:316)

I'm using a basic example using the ExamplePointUdt from spark framework:

  test("udt serialisation") {
    val points = Seq(new ExamplePoint(1.3, 1.6), new ExamplePoint(1.3, 1.8))
    val df = SparkContextForStdout.context.parallelize(points).toDF()
  }
