[jira] [Created] (IMPALA-7837) SCAN_BYTES_LIMIT="100M" test failing to raise exception in release build

Michael Brown created IMPALA-7837:
-------------------------------------

             Summary: SCAN_BYTES_LIMIT="100M" test failing to raise exception in release build
                 Key: IMPALA-7837
                 URL: https://issues.apache.org/jira/browse/IMPALA-7837
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 3.1.0
            Reporter: Michael Brown
            Assignee: Bikramjeet Vig
         Attachments: impala-logs.tar.gz

This test is not raising the expected exception on a *release build*:
{noformat}
---- QUERY
# Query should fail due to exceeding scan bytes limit.
set SCAN_BYTES_LIMIT="100M";
select count(*) from tpch.lineitem l1,tpch.lineitem l2, tpch.lineitem l3 where
 l1.l_suppkey = l2.l_linenumber and l1.l_orderkey = l2.l_orderkey and
 l1.l_orderkey = l3.l_orderkey group by l1.l_comment, l2.l_comment
 having count(*) = 99
---- CATCH
row_regex:.*terminated due to scan bytes limit of 100.00 M.
{noformat}

{noformat}
Stacktrace
query_test/test_resource_limits.py:46: in test_resource_limits
    self.run_test_case('QueryTest/query-resource-limits', vector)
common/impala_test_suite.py:482: in run_test_case
    assert False, "Expected exception: %s" % expected_str
E   AssertionError: Expected exception: row_regex:.*terminated due to scan bytes limit of 100.00 M.*
{noformat}

It fails deterministically in CI (3 times in a row). I can't find a query profile matching the query ID for some reason, but I've attached logs.
