-------------------------------------
Hi [~brkyvz], can you verify if this bug still exists? I can't reproduce it on
master.
> Attribute reference mismatch with Dataset filter + mapPartitions
> ----------------------------------------------------------------
>
> Key: SPARK-14766
> URL: https://issues.apache.org/jira/browse/SPARK-14766
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Burak Yavuz
>
> 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}
