Summary: ProjectExec has incorrect outputOrdering property
Key: SPARK-17956
URL: https://issues.apache.org/jira/browse/SPARK-17956
Project: Spark
Issue Type: Bug
Components: SQL

Currently ProjectExec simply takes child plan's outputOrdering as its
outputOrdering. In some cases, this leads to incorrect outputOrdering. This
applies to TakeOrderedAndProjectExec too.
