Yin Huai created SPARK-9949:
-------------------------------
Summary: TakeOrderedAndProject returns wrong output attributes
when project is pushed in to it
Key: SPARK-9949
URL: https://issues.apache.org/jira/browse/SPARK-9949
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Yin Huai
Assignee: Yin Huai
Priority: Blocker
In {{TakeOrderedAndProject}}, we have
{code}
case class TakeOrderedAndProject(
limit: Int,
sortOrder: Seq[SortOrder],
projectList: Option[Seq[NamedExpression]],
child: SparkPlan) extends UnaryNode {
override def output: Seq[Attribute] = child.output
{code}
When projectList is set, we should use its attributes as the output.
