Can you please provide a screenshot or some explanation that is more clear? This is really difficult to follow.

I'm not yet convinced there is a bug in Drill here. I think the issue may actually be in your query. My hunch here is that there may be an issue in the ORDER BY statement. Your inner tables each have columns called k1. Then you are calling a sort on that without specifying which one it is. You might first try adding table names to the ORDER BY clause.
Secondly, I'm not trying to be rude but what are you trying to achieve with this query? It looks like you are performing a union of a left and right join of the same table? Why not combine these? Then you have nested SELECT * statements that don't really seem to serve any purpose.
This is a test case written by testers, without actual usage scenarios. What do you mean by combining them?
