Hyukjin Kwon resolved SPARK-14766.
----------------------------------
    Resolution: Cannot Reproduce

{code}
scala> Seq((1, 1)).toDS().filter(_._1 != 0).mapPartitions { iter => iter }.count()
res4: Long = 1
{code}

I can't reproduce this too.

> After a filter, the Dataset references seem to be not copied properly leading to an exception. To reproduce, you may use the following code:
> {code}
> Seq((1, 1)).toDS().filter(_._1 != 0).mapPartitions { iter => iter }.count()
> {code}
> Using explain shows the problem:
> {code}
> == Physical Plan ==
> !MapPartitions <function1>, newInstance(class scala.Tuple2), [input[0, scala.Tuple2]._1 AS _1#38521,input[0, scala.Tuple2]._2 AS _2#38522]
> +- WholeStageCodegen
>    :  +- Filter <function1>.apply
>    :     +- INPUT
>    +- LocalTableScan [_1#38512,_2#38513], [[0,1,1]]
> {code}
