Impala Public Jenkins,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: IMPALA-8533: Impala daemon crash on sort

IMPALA-8533: Impala daemon crash on sort

This crash was caused by an empty sort tuple descriptor that was
generated as a result of union substitutions replacing all sort
fields with literals that were subsequently removed from the ordering
spec. There was no check in place to prevent the empty tuple descriptor
from being sent to impalad where it caused a divide-by-zero crash.

This fix avoids inserting a sort node when there are no fields remaining
to sort on. Also added a precondition to the SortNode that will prevent
similar issues from crashing impalad.

Testing:
Testcases added to PlannerTest/union.test
