[jira] [Updated] (SPARK-7701) UDT not working

     [ https://issues.apache.org/jira/browse/SPARK-7701?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

bogdan baraila updated SPARK-7701:
----------------------------------
    Description: 
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:
{code}
  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()
  }
{code}
