Description

We had a recent test failure in test_mem_limit:

 

custom_cluster/test_admission_controller.py:1504: in test_mem_limit
    {'request_pool': self.pool_name, 'mem_limit': query_mem_limit})
custom_cluster/test_admission_controller.py:1365: in run_admission_test
    assert metric_deltas['dequeued'] == 0,\
E   AssertionError: Queued queries should not run until others are made to finish
E   assert 3 == 0

assert 7 >= 10  +  where 10 = min((30 - 5), 10)

Stacktrace

custom_cluster/test_admission_controller.py:1504: in test_mem_limit
    {'request_pool': self.pool_name, 'mem_limit': query_mem_limit})
custom_cluster/test_admission_controller.py:1384: in run_admission_test
    assert queries_page_num_queued >=\
E   assert 7 >= 10
E    +  where 10 = min((30 - 5), 10)

It looks like this was a release build.

test1.txt was master
test2.txt was 2.12 with a bunch of cloudera patches
