-----------------------------------------
The previous [patch|http://gerrit.cloudera.org:8080/17256] finally allowed the
actual error to be logged.

custom_cluster/test_admission_controller.py:2078: in test_mem_limit
{'request_pool': self.pool_name, 'mem_limit': query_mem_limit})
custom_cluster/test_admission_controller.py:1936: in run_admission_test
assert metric_deltas['dequeued'] == 0,\
E AssertionError: Queued queries should not run until others are made to
finish
E assert 4 == 0
{noformat}
As I suspected, after turning on result spooling by default the queries are
finishing early and releasing resources which allows queued queries to run.
This test uses a long running query that returns a lot of rows to control
resources being held and result spooling messes with that control. Since
adapting this to result spooling would not add any test coverage benefit, we
can just turn it off for these stress tests.
