-----------------------------------

             Summary: TestExchangeMemUsage.test_exchange_mem_usage_scaling doesn't hit the memory limit
                 Key: IMPALA-9355
                 URL: https://issues.apache.org/jira/browse/IMPALA-9355
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Fang-Yu Rao
            Assignee: Joe McDonnell


The EE test {{test_exchange_mem_usage_scaling}} failed because the query at [https://github.com/apache/impala/blame/master/testdata/workloads/functional-query/queries/QueryTest/exchange-mem-scaling.test#L7-L15] does not hit the specified memory limit (170m) at [https://github.com/apache/impala/blame/master/testdata/workloads/functional-query/queries/QueryTest/exchange-mem-scaling.test#L7]. We may need to further reduce the specified limit. In what follows the error message is also given.
