---------------------------------------
[~szita]: commit to spark branch, thanks! for the question
{quote}
Is there any reason why we're sorting the leaves of a plan in-place instead of
taking a copy of them and then doing it
[here|https://github.com/apache/pig/blob/trunk/src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/plans/PlanPrinter.java#L137]?

yes, i am also very curious about this, if the result of $${mPlan.getLeaves()}}
is sorted by OperatorKey, we can remove some Collections.sort(leaves)
operations.
