> Key: IMPALA-6736
> URL: https://issues.apache.org/jira/browse/IMPALA-6736
> Project: IMPALA
> Issue Type: Task
> Components: Infrastructure
> Affects Versions: Impala 2.8.0
> Reporter: Michael Brown
> Assignee: Michael Brown
> Priority: Major
> Fix For: Impala 3.0, Impala 2.12.0
>
>
> In testing https://gerrit.cloudera.org/#/c/9758/ I noticed that TPC-DS Q67A
> at SF 300 takes 49525M to run without spilling. This is an order of magnitude
> larger than any other query. The query is too large for the cluster to also
> stress the cluster concurrency-wise.
> The stress test has an option that in theory is supposed to catch this
> {noformat}
> --filter-query-mem-ratio FILTER_QUERY_MEM_RATIO
> Queries that require this ratio of total available
> memory will be filtered. (default: 0.333)
> {noformat}
> but it's broken. Fix/improve the option.
