Issue Type: Bug
Affects Versions: Impala 4.0

We found in a recent build that a test case in
[test_basic_joins()|https://github.infra.cloudera.com/CDH/Impala/blob/cdpd-master-staging/tests/query_test/test_join_queries.py#L71]
does not fail with the expected error.

Standard Error

According to the output to standard error, two related queries are of query
id's {{1a49038843b6b4da:30f6228100000000}} and
{{9f4e869839247e75:d01b009300000000}}.
Using these two query id's, we excerpted the related log entries from two log
files of impalad's.
Since this test was recently revised in IMPALA-9309, maybe [~tarmstrong] could
offer some insight into it. Assigned it to Tim for now but feel free to
re-assign it as you see appropriate. Also let me know if some other logs are
needed for investigation. Thanks!
