> We don't have a good regression test for IMPALA-2376. With IMPALA-4835 and
> other changes it's increasingly difficult to get the query to OOM at the
> intended place. We probably need to construct some special test data with a
> very large nested collection to trigger this bug.
> This is based on the TODO:
> {noformat}
> ====
> ---- QUERY
> # IMPALA-2376
> # Set memory limit low enough to get the below query to consistently fail.
> # TODO: change query and/or table so we can consistently check for the
> following error:
> # Failed to allocate buffer for collection '...'.
> set mem_limit=4m;
> select max(cnt) from customer c,
> (select count(l_returnflag) cnt from c.c_orders.o_lineitems) v;
> ---- TYPES
> BIGINT
> ---- CATCH
> Memory limit exceeded
> {noformat}
