Hello Dan Hecht,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).
Change subject: IMPALA-5562: Only recomputeMemLayout() if tuple has a layout.
......................................................................
IMPALA-5562: Only recomputeMemLayout() if tuple has a layout.
For queries where plan generation is terminated early due to LIMIT 0
or similar, some tuples may not have a mem layout because no PlanNode
has been generated to materialize them. The fix is to make
recomputeMemLayout() a no-op if the tuple does not have an existing
mem layout.
Testing:
- added regression test
