Michael Brown created IMPALA-6736:
-------------------------------------
Summary: stress test --filter-query-mem-ratio doesn't work
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
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.
