Please take a look at createTaskResult() in
core/src/test/scala/org/apache/spark/scheduler/TaskSetManagerSuite.scala :
```
def createTaskResult(id: Int): DirectTaskResult[Int] = {
val valueSer = SparkEnv.get.serializer.newInstance()
new DirectTaskResult[Int](valueSer.serialize(id), mutable.Map.empty,
new TaskMetrics)
}
```
