             Summary: 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


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.
