Ian updated SPARK-12258:
------------------------
    Description: 
{code}
  test("Timestamp UDF and Null value") {
    hiveContext.runSqlHive("CREATE TABLE ts_test (ts TIMESTAMP) STORED AS 
TEXTFILE")
    hiveContext.runSqlHive("INSERT INTO TABLE ts_test VALUES(Null)")
    hiveContext.udf.register("dummy",
      (ts: Timestamp) => ts
    )
    val result = hiveContext.sql("SELECT dummy(ts) FROM 
ts_test").collect().mkString("\n")
    assertResult("[null]")(result)
  }
{code}

  was:
  test("Timestamp UDF and Null value") {
    hiveContext.runSqlHive("CREATE TABLE ts_test (ts TIMESTAMP) STORED AS 
TEXTFILE")
    hiveContext.runSqlHive("INSERT INTO TABLE ts_test VALUES(Null)")
    hiveContext.udf.register("dummy",
      (ts: Timestamp) => ts
    )
    val result = hiveContext.sql("SELECT dummy(ts) FROM 
ts_test").collect().mkString("\n")
    assertResult("[null]")(result)
  }
