-------------------------------------
Assignee: Joe McDonnell
> Extend slot based admission to default executor group
> -----------------------------------------------------
>
> Key: IMPALA-8757
> URL: https://issues.apache.org/jira/browse/IMPALA-8757
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 3.3.0
> Reporter: Lars Volker
> Assignee: Joe McDonnell
> Priority: Major
> Labels: admission-control, compatibility, scalability
>
> IMPALA-8484 adds support for multiple executor groups and uses a slot-based
> mechanism to admit queries to executors. In order to keep the existing
> behavior stable, this logic is not applied to the default executor group.
> This Jira tracks work on doing that. We have to be careful not to break the
> existing behavior, and if we do, hold the change back until the next
> compatibility-breaking release.
