             Summary: Stress test for memory-based admission control
                 Key: IMPALA-7356
                 URL: https://issues.apache.org/jira/browse/IMPALA-7356
             Project: IMPALA
          Issue Type: Test
          Components: Infrastructure
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


We should extend the existing stress test to have a new mode designed to test memory-based admission control, where the stress test framework does not try to throttle memory consumption but instead relies on Impala doing so. 

The required changes would be:
* A mode to disable throttling
* Options for stricter pass conditions - queries should not fail with OOM even if the stress test tries to submit way too many queries. 
* However AC queue timeouts may be ok.
* Investigation into the logic for choosing which query to run next and when - does that need to change?
