Rajesh Balamohan commented on SPARK-14752:
------------------------------------------
Changing generatedOrdering in LazilyGeneratedOrdering to
{noformat}
private[this] lazy val generatedOrdering = GenerateOrdering.generate(ordering)
{noformat}
solves the issue and the query runs fine.
> LazilyGenerateOrdering throws NullPointerException with TakeOrderedAndProject
