             Summary: 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}
