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

Hi, [~XuanYuan].
Could you check old Spark versions and update `Affects Version/s:` of this JIRA 
issue?

> It's another case for the indeterminate stage/RDD rerun while stage rerun 
> happened. In the CachedRDDBuilder, we miss tracking the `isOrderSensitive` 
> characteristic to the newly created MapPartitionsRDD.
> We can reproduce this by the following code, thanks to Tyson for reporting 
> this!
>  
> {code:scala}
> import scala.sys.process._
> import org.apache.spark.TaskContext
> val res = spark.range(0, 10000 * 10000, 1).map\{ x => (x % 1000, x)}
> // kill an executor in the stage that performs repartition(239)
> val df = res.repartition(113).cache.repartition(239).map { x =>
>  if (TaskContext.get.attemptNumber == 0 && TaskContext.get.partitionId < 1 && 
> TaskContext.get.stageAttemptNumber == 0) {
>  throw new Exception("pkill -f -n java".!!)
>  }
>  x
> }
> val r2 = df.distinct.count()
> {code}
