Review comment:
I don't think there will be many duplications: we just create a task array
and put it in TaskSet
```
Array.tabulate[Task[_]](numTasks)(new FakeLongTasks(_))
...
class FakeLongTasks(partitionId: Int)
extends Task[Int](0, 0, partitionId, new Properties,
SparkEnv.get.closureSerializer.newInstance().serialize(TaskMetrics.registered).array(),
false) ...
```
