Resolution: Won't Do
> Support using non-default executor groups for planner
> -----------------------------------------------------
>
> Key: IMPALA-12312
> URL: https://issues.apache.org/jira/browse/IMPALA-12312
> Project: IMPALA
> Issue Type: Improvement
> Reporter: YifanZhang
> Priority: Minor
>
> An Impala cluster can contain multiple executor group sets, including a
> default executor group and non-default executor groups. The current planner
> always tends to pick the default executor group for scheduling a query
> because only the default executor group is included in the update message
> that is sent to the frontend.
> When we set a non-default request_pool for a query, the generated plan is
> still based on the default executor group, which leads to an inaccurate
> execution plan.
> This can be improved by sending all configured executor groups' information
> to the frontend.
