-----------------------------------
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}
