-----------------------------------
Assignee: Liang-Chi Hsieh
> InMemoryTableScanExec should rewrite output partitioning and ordering when
> aliasing output attributes
> -----------------------------------------------------------------------------------------------------
>
> Key: SPARK-19931
> URL: https://issues.apache.org/jira/browse/SPARK-19931
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Liang-Chi Hsieh
> Assignee: Liang-Chi Hsieh
> Fix For: 2.2.0
>
>
> Now InMemoryTableScanExec simply takes the outputPartitioning and
> outputOrdering from the associated InMemoryRelation's
> child.outputPartitioning and outputOrdering.
> However, InMemoryTableScanExec can alias the output attributes. In this case,
> its outputPartitioning and outputOrdering are not correct and its parent
> operators can't correctly determine its data distribution.
