[jira] [Created] (IMPALA-8757) Extend slot based admission to default executor group

Lars Volker created IMPALA-8757:
-----------------------------------

             Summary: 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


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.
