Zoltán Borók-Nagy reopened IMPALA-9355:
---------------------------------------
> 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: Qifan Chen
> Priority: Critical
> Labels: broken-build, flaky
> Fix For: Impala 4.0
>
>
> 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. Recall that the same issue occurred at
> https://issues.apache.org/jira/browse/IMPALA-7873 but was resolved.
