> 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.
